Usage: build-locale-archive [OPTION]... [TEMPLATE-FILE] [ARCHIVE-FILE]\n\
|
|
||||||
Builds a locale archive from a template file.\n\
|
|
||||||
Options:\n\
|
|
||||||
-h, --help Print this usage message.\n\
|
|
||||||
-v, --verbose Verbose execution.\n\
|
|
||||||
-l, --install-langs=LIST Only include locales given in LIST into the \n\
|
|
||||||
locale archive. LIST is a colon separated list\n\
|
|
||||||
of locale prefixes, for example \"de:en:ja\".\n\
|
|
||||||
The special argument \"all\" means to install\n\
|
|
||||||
all languages and it must be present by itself.\n\
|
|
||||||
If \"all\" is present with any other language it\n\
|
|
||||||
will be treated as the name of a locale.\n\
|
|
||||||
If the --install-langs option is missing, all\n\
|
|
||||||
locales are installed. The colon separated list\n\
|
|
||||||
can contain any strings matching the beginning of\n\
|
|
||||||
locale names.\n\
|
|
||||||
If a string does not contain a \"_\", it is added.\n\
|
|
||||||
Examples:\n\
|
|
||||||
--install-langs=\"en\"\n\
|
|
||||||
installs en_US, en_US.iso88591,\n\
|
|
||||||
en_US.iso885915, en_US.utf8,\n\
|
|
||||||
en_GB ...\n\
|
|
||||||
--install-langs=\"en_US.utf8\"\n\
|
|
||||||
installs only en_US.utf8.\n\
|
|
||||||
--install-langs=\"ko\"\n\
|
|
||||||
installs ko_KR, ko_KR.euckr,\n\
|
|
||||||
ko_KR.utf8 but *not* kok_IN\n\
|
|
||||||
because \"ko\" does not contain\n\
|
|
||||||
\"_\" and it is silently added\n\
|
|
||||||
--install-langs\"ko:kok\"\n\
|
|
||||||
installs ko_KR, ko_KR.euckr,\n\
|
|
||||||
ko_KR.utf8, kok_IN, and\n\
|
|
||||||
kok_IN.utf8.\n\
|
|
||||||
--install-langs=\"POSIX\" will\n\
|
|
||||||
installs *no* locales at all\n\
|
|
||||||
because POSIX matches none of\n\
|
|
||||||
the locales. Actually, any string\n\
|
|
||||||
matching nothing will do that.\n\
|
|
||||||
POSIX and C will always be\n\
|
|
||||||
available because they are\n\
|
|
||||||
builtin.\n\
|
|
||||||
Aliases are installed as well,\n\
|
|
||||||
i.e. --install-langs=\"de\"\n\
|
|
||||||
will install not only every locale starting with\n\
|
|
||||||
\"de\" but also the aliases \"deutsch\"\n\
|
|
||||||
and and \"german\" although the latter does not\n\
|
|
||||||
start with \"de\".\n\
|
|
||||||
\n\
|
|
||||||
If the arguments TEMPLATE-FILE and ARCHIVE-FILE are not given the locations\n\
|
|
||||||
where the glibc used expects these files are used by default.\n\

commit f5117c6504888fab5423282a4607c552b90fd3f9
|
||||||
|
Author: Carlos O'Donell <carlos@redhat.com>

|
||||||
|
|
||||||
|
Add 'codepoint_collation' support for LC_COLLATE.
|
||||||
|
|
||||||
|
Support a new directive 'codepoint_collation' in the LC_COLLATE
|
||||||
|
section of a locale source file. This new directive causes all
|
||||||
|
collation rules to be dropped and instead STRCMP (strcmp or
|
||||||
|
wcscmp) is used for collation of the input character set. This
|
||||||
|
is required to allow for a C.UTF-8 that contains zero collation
|
||||||
|
rules (minimal size) and sorts using code point sorting.
|
||||||
|
|
||||||
|
To date the only implementation of a locale with zero collation
|
||||||
|
rules is the C/POSIX locale. The C/POSIX locale provides
|
||||||
|
identity tables for _NL_COLLATE_COLLSEQMB and
|
||||||
|
_NL_COLLATE_COLLSEQWC that map to ASCII even though it has zero
|
||||||
|
rules. This has lead to existing fnmatch, regexec, and regcomp
|
||||||
|
implementations that require these tables. It is not correct
|
||||||
|
to use these tables when nrules == 0, but the conservative fix
|
||||||
|
is to provide these tables when nrules == 0. This assures that
|
||||||
|
existing static applications using a new C.UTF-8 locale with
|
||||||
|
'codepoint_collation' at least have functional range expressions
|
||||||
|
with ASCII e.g. [0-9] or [a-z]. Such static applications would
|
||||||
|
not have the fixes to fnmatch, regexec and regcomp that avoid
|
||||||
|
the use of the tables when nrules == 0. Future fixes to fnmatch,
|
||||||
|
regexec, and regcomp would allow range expressions to use the
|
||||||
|
full set of code points for such ranges.
|
||||||
|
|
||||||
|
Tested on x86_64 and i686 without regression.

localedef: Fix handling of empty mon_decimal_point (Bug 28847)
|
||||||
|
|
||||||
|
The handling of mon_decimal_point is incorrect when it comes to
|
||||||
|
handling the empty "" value. The existing parser in monetary_read()
|
||||||
|
will correctly handle setting the non-wide-character value and the
|
||||||
|
wide-character value e.g. STR_ELEM_WC(mon_decimal_point) if they are
|
||||||
|
set in the locale definition. However, in monetary_finish() we have
|
||||||
|
conflicting TEST_ELEM() which sets a default value (if the locale
|
||||||
|
definition doesn't include one), and subsequent code which looks for
|
||||||
|
mon_decimal_point to be NULL to issue a specific error message and set
|
||||||
|
the defaults. The latter is unused because TEST_ELEM() always sets a
|
||||||
|
default. The simplest solution is to remove the TEST_ELEM() check,
|
||||||
|
and allow the existing check to look to see if mon_decimal_point is
|
||||||
|
NULL and set an appropriate default. The final fix is to move the
|
||||||
|
setting of mon_decimal_point_wc so it occurs only when
|
||||||
|
mon_decimal_point is being set to a default, keeping both values
|
||||||
|
consistent. There is no way to tell the difference between
|
||||||
|
mon_decimal_point_wc having been set to the empty string and not
|
||||||
|
having been defined at all, for that distinction we must use
|
||||||
|
mon_decimal_point being NULL or "", and so we must logically set
|
||||||
|
the default together with mon_decimal_point.
|
||||||
|
|
||||||
|
Lastly, there are more fixes similar to this that could be made to
|
||||||
|
ld-monetary.c, but we avoid that in order to fix just the code
|
||||||
|
required for mon_decimal_point, which impacts the ability for C.UTF-8
|
||||||
|
to set mon_decimal_point to "", since without this fix we end up with
|
||||||
|
an inconsistent setting of mon_decimal_point set to "", but
|
||||||
|
mon_decimal_point_wc set to "." which is incorrect.
|
||||||
|
|
||||||
|
Tested on x86_64 and i686 without regression.

commit de82cb0da4b8fa5b3d56c457438d2568c67ab1b1

Add TEST_COMPARE_STRING_WIDE to support/check.h
|
||||||
|
|
||||||
|
I'd like to be able to test narrow and wide string interfaces, with
|
||||||
|
the narrow string tests using TEST_COMPARE_STRING and the wide string
|
||||||
|
tests using something analogous (possibly generated using macros from
|
||||||
|
a common test template for both the narrow and wide string tests where
|
||||||
|
appropriate).
|
||||||
|
|
||||||
|
Add such a TEST_COMPARE_STRING_WIDE, along with functions
|
||||||
|
support_quote_blob_wide and support_test_compare_string_wide that it
|
||||||
|
builds on. Those functions are built using macros from common
|
||||||
|
templates shared by the narrow and wide string implementations, though
|
||||||
|
I didn't do that for the tests of test functions. In
|
||||||
|
support_quote_blob_wide, I chose to use the \x{} delimited escape
|
||||||
|
sequence syntax proposed for C2X in N2785, rather than e.g. trying to
|
||||||
|
generate the end of a string and the start of a new string when
|
||||||
|
ambiguity would result from undelimited \x (when the next character
|
||||||
|
after such an escape sequence is valid hex) or forcing an escape
|
||||||
|
sequence to be used for the next character in the case of such
|
||||||
|
ambiguity.
|
||||||
|
|
||||||
|
Tested for x86_64.

localedata: Adjust C.UTF-8 to align with C/POSIX.
|
||||||
|
|
||||||
|
We have had one downstream report from Canonical [1] that
|
||||||
|
an rrdtool test was broken by the differences in LC_TIME
|
||||||
|
that we had in the non-builtin C locale (C.UTF-8). If one
|
||||||
|
application has an issue there are going to be others, and
|
||||||
|
so with this commit we review and fix all the issues that
|
||||||
|
cause the builtin C locale to be different from C.UTF-8,
|
||||||
|
which includes:
|
||||||
|
* mon_decimal_point should be empty e.g. ""
|
||||||
|
- Depends on mon_decimal_point_wc fix.
|
||||||
|
* negative_sign should be empty e.g. ""
|
||||||
|
* week should be aligned with the builtin C/POSIX locale
|
||||||
|
* d_fmt corrected with escaped slashes e.g. "%m//%d//%y"
|
||||||
|
* yesstr and nostr should be empty e.g. ""
|
||||||
|
* country_ab2 and country_ab3 should be empty e.g. ""
|
||||||
|
|
||||||
|
We bump LC_IDENTIFICATION version and adjust the date to
|
||||||
|
indicate the change in the locale.
|
||||||
|
|
||||||
|
A new tst-c-utf8-consistency test is added to ensure
|
||||||
|
consistency between C/POSIX and C.UTF-8.
|
||||||
|
|
||||||
|
Tested on x86_64 and i686 without regression.

Short description: Add C.UTF-8 support.
|
|
||||||
Author(s): Fedora glibc team <glibc@lists.fedoraproject.org>
|
|
||||||
Origin: PATCH
|
|
||||||
Upstream status: not-submitted
|
|
||||||
|
|
||||||
This patch needs to upstream as part of Carlos O'Donell
|
|
||||||
<carlos@redhat.com>'s work on enabling upstream C.UTF-8 support. This
|
|
||||||
work is currently blocked on cleaning up the test results to prove that
|
|
||||||
full code-point sorting is working as intended.
|
|
||||||
|
|
||||||
Note that this patch does not provide full code-point sorting as
|
|
||||||
expected.
|
|
||||||
|
|
||||||
This patch needs to upstream as soon as possible since it would be nice
|
|
||||||
to have this in F29 and fixed.

This patch needs to go upstream to get cleaned up, but has always involed
|
|
||||||
analysis of the GNU/Hurd parts of the change and that stalled out, but
|
|
||||||
perhaps with build-many-glibcs we can now test these changes more easily.

support: Add signal support to support_capture_subprocess_check
|
|
||||||
|
|
||||||
Signal zero does not terminate a process, so it is safe to use negative
|
|
||||||
values for signal numbers.
|
|
||||||
|
|
||||||
Adjust libio/tst-vtables-common.c to use this new functionality,
|
|
||||||
instead of determining the termination status for a signal indirectly.

dlopen: Rework handling of pending NODELETE status
|
|
||||||
|
|
||||||
Commit a2e8aa0d9ea648068d8be52dd7b15f1b6a008e23 ("Block signals during
|
|
||||||
the initial part of dlopen") was deemed necessary because of
|
|
||||||
read-modify-write operations like the one in add_dependency in
|
|
||||||
elf/dl-lookup.c. In the old code, we check for any kind of NODELETE
|
|
||||||
status and bail out:
|
|
||||||
|
|
||||||
/* Redo the NODELETE check, as when dl_load_lock wasn't held
|
|
||||||
yet this could have changed. */
|
|
||||||
if (map->l_nodelete != link_map_nodelete_inactive)
|
|
||||||
goto out;
|
|
||||||
|
|
||||||
And then set pending status (during relocation):
|
|
||||||
|
|
||||||
if (flags & DL_LOOKUP_FOR_RELOCATE)
|
|
||||||
map->l_nodelete = link_map_nodelete_pending;
|
|
||||||
else
|
|
||||||
map->l_nodelete = link_map_nodelete_active;
|
|
||||||
|
|
||||||
If a signal arrives during relocation and the signal handler, through
|
|
||||||
lazy binding, adds a global scope dependency on the same map, it will
|
|
||||||
set map->l_nodelete to link_map_nodelete_active. This will be
|
|
||||||
overwritten with link_map_nodelete_pending by the dlopen relocation
|
|
||||||
code.
|
|
||||||
|
|
||||||
To avoid such problems in relation to the l_nodelete member, this
|
|
||||||
commit introduces two flags for active NODELETE status (irrevocable)
|
|
||||||
and pending NODELETE status (revocable until activate_nodelete is
|
|
||||||
invoked). As a result, NODELETE processing in dlopen does not
|
|
||||||
introduce further reasons why lazy binding from signal handlers
|
|
||||||
is unsafe during dlopen, and a subsequent commit can remove signal
|
|
||||||
blocking from dlopen.
|
|
||||||
|
|
||||||
This does not address pre-existing issues (unrelated to the NODELETE
|
|
||||||
changes) which make lazy binding in a signal handler during dlopen
|
|
||||||
unsafe, such as the use of malloc in both cases.

dlopen: Do not block signals
|
|
||||||
|
|
||||||
Blocking signals causes issues with certain anti-malware solutions
|
|
||||||
which rely on an unblocked SIGSYS signal for system calls they
|
|
||||||
intercept.
|
|
||||||
|
|
||||||
This reverts commit a2e8aa0d9ea648068d8be52dd7b15f1b6a008e23
|
|
||||||
("Block signals during the initial part of dlopen") and adds
|
|
||||||
comments related to async signal safety to active_nodelete and
|
|
||||||
its caller.
|
|
||||||
|
|
||||||
Note that this does not make lazy binding async-signal-safe with regards
|
|
||||||
to dlopen. It merely avoids introducing new async-signal-safety hazards
|
|
||||||
as part of the NODELETE changes.

Clear GL(dl_initfirst) when freeing its link_map memory [BZ# 25396]

We should clear GL(dl_initfirst) when freeing its link_map memory.

elf: Add elf/tst-dlopenfail-2 [BZ #25396]
|
|
||||||
|
|
||||||
Without CET, a jump into a newly loaded object through an overwritten
|
|
||||||
link map often does not crash, it just executes some random code.
|
|
||||||
CET detects this in some cases because the function pointer does not
|
|
||||||
point to the start of a function in the replacement shared object,
|
|
||||||
so there is no ENDBR instruction.
|
|
||||||
|
|
||||||
The new test uses a small shared object and the existing dangling
|
|
||||||
link map to trigger the bug.

Enhance _dl_catch_exception to allow disabling exception handling
|
|
||||||
|
|
||||||
In some cases, it is necessary to introduce noexcept regions
|
|
||||||
where raised dynamic loader exceptions (e.g., from lazy binding)
|
|
||||||
are fatal, despite being nested in a code region with an active
|
|
||||||
exception handler. This change enhances _dl_catch_exception with
|
|
||||||
to provide such a capability. The existing function is reused,
|
|
||||||
so that it is not necessary to introduce yet another function with
|
|
||||||
a similar purpose.

Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304]
|
|
||||||
|
|
||||||
If a lazy binding failure happens during the execution of an ELF
|
|
||||||
constructor or destructor, the dynamic loader catches the error
|
|
||||||
and reports it using the dlerror mechanism. This is undesirable
|
|
||||||
because there could be other constructors and destructors that
|
|
||||||
need processing (which are skipped), and the process is in an
|
|
||||||
inconsistent state at this point. Therefore, we have to issue
|
|
||||||
a fatal dynamic loader error error and terminate the process.
|
|
||||||
|
|
||||||
Note that the _dl_catch_exception in _dl_open is just an inner catch,
|
|
||||||
to roll back some state locally. If called from dlopen, there is
|
|
||||||
still an outer catch, which is why calling _dl_init via call_dl_init
|
|
||||||
and a no-exception is required and cannot be avoiding by moving the
|
|
||||||
_dl_init call directly into _dl_open.
|
|
||||||
|
|
||||||
_dl_fini does not need changes because it does not install an error
|
|
||||||
handler, so errors are already fatal there.

Avoid late failure in dlopen in global scope update [BZ #25112]
|
|
||||||
|
|
||||||
The call to add_to_global in dl_open_worker happens after running ELF
|
|
||||||
constructors for new objects. At this point, proper recovery from
|
|
||||||
malloc failure would be quite complicated: We would have to run the
|
|
||||||
ELF destructors and close all opened objects, something that we
|
|
||||||
currently do not do.
|
|
||||||
|
|
||||||
Instead, this change splits add_to_global into two phases,
|
|
||||||
add_to_global_resize (which can raise an exception, called before ELF
|
|
||||||
constructors run), and add_to_global_update (which cannot, called
|
|
||||||
after ELF constructors). A complication arises due to recursive
|
|
||||||
dlopen: After the inner dlopen consumes some space, the pre-allocation
|
|
||||||
in the outer dlopen may no longer be sufficient. A new member in the
|
|
||||||
namespace structure, _ns_global_scope_pending_adds keeps track of the
|
|
||||||
maximum number of objects that need to be added to the global scope.
|
|
||||||
This enables the inner add_to_global_resize call to take into account
|
|
||||||
the needs of an outer dlopen.
|
|
||||||
|
|
||||||
Most code in the dynamic linker assumes that the number of global
|
|
||||||
scope entries fits into an unsigned int (matching the r_nlist member
|
|
||||||
of struct r_scop_elem). Therefore, change the type of
|
|
||||||
_ns_global_scope_alloc to unsigned int (from size_t), and add overflow
|
|
||||||
checks.

Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]
|
|
||||||
|
|
||||||
This change splits the scope and TLS slotinfo updates in dlopen into
|
|
||||||
two parts: one to resize the data structures, and one to actually apply
|
|
||||||
the update. The call to add_to_global_resize in dl_open_worker is moved
|
|
||||||
before the demarcation point at which no further memory allocations are
|
|
||||||
allowed.
|
|
||||||
|
|
||||||
_dl_add_to_slotinfo is adjusted to make the list update optional. There
|
|
||||||
is some optimization possibility here because we could grow the slotinfo
|
|
||||||
list of arrays in a single call, one the largest TLS modid is known.
|
|
||||||
|
|
||||||
This commit does not fix the fatal meory allocation failure in
|
|
||||||
_dl_update_slotinfo. Ideally, this error during dlopen should be
|
|
||||||
recoverable.
|
|
||||||
|
|
||||||
The update order of scopes and TLS data structures is retained, although
|
|
||||||
it appears to be more correct to fully initialize TLS first, and then
|
|
||||||
expose symbols in the newly loaded objects via the scope update.
|
|
||||||
|
|
||||||
Tested on x86_64-linux-gnu.

Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]
|
|
||||||
|
|
||||||
This introduces a “pending NODELETE” state in the link map, which is
|
|
||||||
flipped to the persistent NODELETE state late in dlopen, via
|
|
||||||
activate_nodelete. During initial relocation, symbol binding
|
|
||||||
records pending NODELETE state only. dlclose ignores pending NODELETE
|
|
||||||
state. Taken together, this results that a partially completed dlopen
|
|
||||||
is rolled back completely because new NODELETE mappings are unloaded.
|
|
||||||
|
|
||||||
Tested on x86_64-linux-gnu and i386-linux-gnu.

Block signals during the initial part of dlopen
|
|
||||||
|
|
||||||
Lazy binding in a signal handler that interrupts a dlopen sees
|
|
||||||
intermediate dynamic linker state. This has likely been always
|
|
||||||
unsafe, but with the new pending NODELETE state, this is clearly
|
|
||||||
incorrect. Other threads are excluded via the loader lock, but the
|
|
||||||
current thread is not. Blocking signals until right before ELF
|
|
||||||
constructors run is the safe thing to do.

Linux: Rewrite __old_getdents64 [BZ #23497]
|
|
||||||
|
|
||||||
Commit 298d0e3129c0b5137f4989275b13fe30d0733c4d ("Consolidate Linux
|
|
||||||
getdents{64} implementation") broke the implementation because it does
|
|
||||||
not take into account struct offset differences.
|
|
||||||
|
|
||||||
The new implementation is close to the old one, before the
|
|
||||||
consolidation, but has been cleaned up slightly.

Check multiple NT_GNU_PROPERTY_TYPE_0 notes [BZ #23509]
|
|
||||||
|
|
||||||
Linkers group input note sections with the same name into one output
|
|
||||||
note section with the same name. One output note section is placed in
|
|
||||||
one PT_NOTE segment. Since new linkers merge input .note.gnu.property
|
|
||||||
sections into one output .note.gnu.property section, there is only
|
|
||||||
one NT_GNU_PROPERTY_TYPE_0 note in one PT_NOTE segment with new linkers.
|
|
||||||
Since older linkers treat input .note.gnu.property section as a generic
|
|
||||||
note section and just concatenate all input .note.gnu.property sections
|
|
||||||
into one output .note.gnu.property section without merging them, we may
|
|
||||||
see multiple NT_GNU_PROPERTY_TYPE_0 notes in one PT_NOTE segment with
|
|
||||||
older linkers.
|
|
||||||
|
|
||||||
When an older linker is used to created the program on CET-enabled OS,
|
|
||||||
the linker output has a single .note.gnu.property section with multiple
|
|
||||||
NT_GNU_PROPERTY_TYPE_0 notes, some of which have IBT and SHSTK enable
|
|
||||||
bits set even if the program isn't CET enabled. Such programs will
|
|
||||||
crash on CET-enabled machines. This patch updates the note parser:
|
|
||||||
|
|
||||||
1. Skip note parsing if a NT_GNU_PROPERTY_TYPE_0 note has been processed.
|
|
||||||
2. Check multiple NT_GNU_PROPERTY_TYPE_0 notes.
|
|
||||||
|
|
||||||
[BZ #23509]
|
|
||||||
* sysdeps/x86/dl-prop.h (_dl_process_cet_property_note): Skip
|
|
||||||
note parsing if a NT_GNU_PROPERTY_TYPE_0 note has been processed.
|
|
||||||
Update the l_cet field when processing NT_GNU_PROPERTY_TYPE_0 note.
|
|
||||||
Check multiple NT_GNU_PROPERTY_TYPE_0 notes.
|
|
||||||

Fix stack overflow in tst-setcontext9 (bug 23717)
|
|
||||||
|
|
||||||
The function f1a, executed on a stack of size 32k, allocates an object of
|
|
||||||
size 32k on the stack. Make the stack variables static to reduce
|
|
||||||
excessive stack usage.

Author: Carlos O'Donell <carlos@redhat.com>
|

|
|
||||||
|
|
||||||
Fix tst-setcontext9 for optimized small stacks.
|
|
||||||
|
|
||||||
If the compiler reduces the stack usage in function f1 before calling
|
|
||||||
into function f2, then when we swapcontext back to f1 and continue
|
|
||||||
execution we may overwrite registers that were spilled to the stack
|
|
||||||
while f2 was executing. Later when we return to f2 the corrupt
|
|
||||||
registers will be reloaded from the stack and the test will crash. This
|
|
||||||
was most commonly observed on i686 with __x86.get_pc_thunk.dx and
|
|
||||||
needing to save and restore $edx. Overall i686 has few registers and
|
|
||||||
the spilling to the stack is bound to happen, therefore the solution to
|
|
||||||
making this test robust is to split function f1 into two parts f1a and
|
|
||||||
f1b, and allocate f1b it's own stack such that subsequent execution does
|
|
||||||
not overwrite the stack in use by function f2.
|
|
||||||
|
|
||||||
Tested on i686 and x86_64.

Fix strstr bug with huge needles (bug 23637)
|
|
||||||
|
|
||||||
The generic strstr in GLIBC 2.28 fails to match huge needles. The optimized
|
|
||||||
AVAILABLE macro reads ahead a large fixed amount to reduce the overhead of
|
|
||||||
repeatedly checking for the end of the string. However if the needle length
|
|
||||||
is larger than this, two_way_long_needle may confuse this as meaning the end
|
|
||||||
of the string and return NULL. This is fixed by adding the needle length to
|
|
||||||
the amount to read ahead.
|
|
||||||
|
|
||||||
[BZ #23637]
|
|
||||||
* string/test-strstr.c (pr23637): New function.
|
|
||||||
(test_main): Add tests with longer needles.
|
|
||||||
* string/strcasestr.c (AVAILABLE): Fix readahead distance.
|
|
||||||
* string/strstr.c (AVAILABLE): Likewise.

i386: Use ENTRY and END in start.S [BZ #23606]
|
|

|
|

Wrapping the _start function with ENTRY and END to insert ENDBR32 at
|
|
||||||
function entry when CET is enabled. Since _start now includes CFI,
|
|
||||||
without "cfi_undefined (eip)", unwinder may not terminate at _start

Fix _dl_profile_fixup data-dependency issue (Bug 23690)
|
|
||||||
|
|
||||||
There is a data-dependency between the fields of struct l_reloc_result
|
|
||||||
and the field used as the initialization guard. Users of the guard
|
|
||||||
expect writes to the structure to be observable when they also observe
|
|
||||||
the guard initialized. The solution for this problem is to use an acquire
|
|
||||||
and release load and store to ensure previous writes to the structure are
|
|
||||||
observable if the guard is initialized.
|
|
||||||
|
|
||||||
The previous implementation used DL_FIXUP_VALUE_ADDR (l_reloc_result->addr)
|
|
||||||
as the initialization guard, making it impossible for some architectures
|
|
||||||
to load and store it atomically, i.e. hppa and ia64, due to its larger size.
|
|
||||||
|
|
||||||
This commit adds an unsigned int to l_reloc_result to be used as the new
|
|
||||||
initialization guard of the struct, making it possible to load and store
|
|
||||||
it atomically in all architectures. The fix ensures that the values
|
|
||||||
observed in l_reloc_result are consistent and do not lead to crashes.
|
|
||||||
The algorithm is documented in the code in elf/dl-runtime.c
|
|
||||||
(_dl_profile_fixup). Not all data races have been eliminated.
|
|
||||||
|
|
||||||
Tested with build-many-glibcs and on powerpc, powerpc64, and powerpc64le.

||||||

||||||

Increase timeout of libio/tst-readline
|
|
||||||
|
|
||||||
Increase timeout from the default 20s to 100s. This test makes close to
|
|
||||||
20 million syscalls with distribution:
|
|
||||||
|
|
||||||
12327675 read
|
|
||||||
4143204 lseek
|
|
||||||
929475 close
|
|
||||||
929471 openat
|
|
||||||
92817 fstat
|
|
||||||
1431 write
|
|
||||||
...
|
|
||||||
|
|
||||||
The default timeout assumes each can finish in 1us on average which
|
|
||||||
is not true on slow machines.

Test stdlib/test-bz22786 exits now with unsupported if malloc fails.
|
|
||||||
|
|
||||||
The test tries to allocate more than 2^31 bytes which will always fail on s390
|
|
||||||
as it has maximum 2^31bit of memory.
|
|
||||||
Before commit 6c3a8a9d868a8deddf0d6dcc785b6d120de90523, this test returned
|
|
||||||
unsupported if malloc fails. This patch re enables this behaviour.
|
|
||||||
|
|
||||||
Furthermore support_delete_temp_files() failed to remove the temp directory
|
|
||||||
in this case as it is not empty due to the created symlink.
|
|
||||||
Thus the creation of the symlink is moved behind malloc.

stdlib/test-bz22786: Avoid spurious test failures using alias mappings
|
|
||||||
|
|
||||||
On systems without enough random-access memory, stdlib/test-bz22786
|
|
||||||
will go deeply into swap and time out, even with a substantial
|
|
||||||
TIMEOUTFACTOR. This commit adds a facility to construct repeating
|
|
||||||
strings with alias mappings, so that the requirement for physical
|
|
||||||
memory, and uses it in stdlib/test-bz22786.
|
|
||||||
|
|
||||||
Adjusted here for conflicts due to the previous support/ backport in
|
|
||||||
glibc-rh1638523-1.patch.

memusagestat: use local glibc when linking [BZ #18465]
|
|
||||||
|
|
||||||
The memusagestat is the only binary that has its own link line which
|
|
||||||
causes it to be linked against the existing installed C library. It
|
|
||||||
has been this way since it was originally committed in 1999, but I
|
|
||||||
don't see any reason as to why. Since we want all the programs we
|
|
||||||
build locally to be against the new copy of glibc, change the build
|
|
||||||
to be like all other programs.

benchtests: Enable BIND_NOW if configured with --enable-bind-now
|
|
||||||
|
|
||||||
Benchmarks should reflect distribution build policies, so it makes
|
|
||||||
sense to honor the BIND_NOW configuration for them.
|
|
||||||
|
|
||||||
This commit keeps using $(+link-tests), so that the benchmarks are
|
|
||||||
linked according to the --enable-hardcoded-path-in-tests configure
|
|
||||||
option.

Makeconfig: Move -Wl,-rpath-link options before library references
|
|
||||||
|
|
||||||
Previously, the -Wl,-rpath-link options came after the libraries
|
|
||||||
injected using LDLIBS-* variables on the link editor command line for
|
|
||||||
main programs. As a result, it could happen that installed libraries
|
|
||||||
that reference glibc libraries used the installed glibc from the system
|
|
||||||
directories, instead of the glibc from the build tree. This can lead to
|
|
||||||
link failures if the wrong version of libpthread.so.0 is used, for
|
|
||||||
instance, due to differences in the internal GLIBC_PRIVATE interfaces,
|
|
||||||
as seen with memusagestat and -lgd after commit
|
|
||||||
f9b645b4b0a10c43753296ce3fa40053fa44606a ("memusagestat: use local glibc
|
|
||||||
when linking [BZ #18465]").
|
|
||||||
|
|
||||||
The isolation is necessarily imperfect because these installed
|
|
||||||
libraries are linked against the installed glibc in the system
|
|
||||||
directories. However, in most cases, the built glibc will be newer
|
|
||||||
than the installed glibc, and this link is permitted because of the
|
|
||||||
ABI backwards compatibility glibc provides.

x86: Fix Haswell strong flags (BZ#23709)
|
|
||||||
|
|
||||||
Th commit 'Disable TSX on some Haswell processors.' (2702856bf4) changed the
|
|
||||||
default flags for Haswell models. Previously, new models were handled by the
|
|
||||||
default switch path, which assumed a Core i3/i5/i7 if AVX is available. After
|
|
||||||
the patch, Haswell models (0x3f, 0x3c, 0x45, 0x46) do not set the flags
|
|
||||||
Fast_Rep_String, Fast_Unaligned_Load, Fast_Unaligned_Copy, and
|
|
||||||
Prefer_PMINUB_for_stringop (only the TSX one).
|
|
||||||
|
|
||||||
This patch fixes it by disentangle the TSX flag handling from the memory
|
|
||||||
optimization ones. The strstr case cited on patch now selects the
|
|
||||||
__strstr_sse2_unaligned as expected for the Haswell cpu.
|
|
||||||
|
|
||||||
Checked on x86_64-linux-gnu.

malloc: tcache: Validate tc_idx before checking for double-frees [BZ #23907]
|
|
||||||
|
|
||||||
The previous check could read beyond the end of the tcache entry
|

array. If the e->key == tcache cookie check happened to pass, this
|
|
||||||
would result in crashes.

powerpc64: Add memory protection key support [BZ #23202]
|
|
||||||
|
|
||||||
The 32-bit protection key behavior is somewhat unclear on 32-bit powerpc,
|
|
||||||
so this change is restricted to the 64-bit variants.
|
|
||||||
|
|
||||||
Flag translation is needed because of hardware differences between the
|
|
||||||
POWER implementation (read and write flags) and the Intel implementation
|
|
||||||
(write and read+write flags).

Fix tst-pkey expectations on pkey_get [BZ #23202]
|
|
||||||
|
|
||||||
From the GNU C Library manual, the pkey_set can receive a combination of
|
|
||||||
PKEY_DISABLE_WRITE and PKEY_DISABLE_ACCESS. However PKEY_DISABLE_ACCESS
|
|
||||||
is more restrictive than PKEY_DISABLE_WRITE and includes its behavior.
|
|
||||||
|
|
||||||
The test expects that after setting
|
|
||||||
(PKEY_DISABLE_WRITE|PKEY_DISABLE_ACCESS) pkey_get should return the
|
|
||||||
same. This may not be true as PKEY_DISABLE_ACCESS will succeed in
|
|
||||||
describing the state of the key in this case.
|
|
||||||
|
|
||||||
The pkey behavior during signal handling is different between x86 and
|
|
||||||
POWER. This change make the test compatible with both architectures.

POWER: Add context-synchronizing instructions to pkey_write [BZ #25954]
|
|

Sandipan Das reported that,
|
|
||||||
|
|
||||||
"The Power ISA mandates that all writes to the Authority
|
|
||||||
Mask Register (AMR) must always be preceded as well as
|
|
||||||
succeeded by a context-synchronizing instruction. This
|
|
||||||
applies to both the privileged and unprivileged variants
|
|
||||||
of the Move To AMR instruction.
|
|
||||||
|
|
||||||
This [requirement] is from Table 6 of Chapter 11 in page 1134 of Power
|

||||||
In function maybe_script_execute, the new_argv array is dynamically
|
|
||||||
initialized on stack with (argc + 1) elements.
|
|
||||||
The function wants to add _PATH_BSHELL as the first argument
|
|
||||||
and writes out of bounds of new_argv.
|
|
||||||
There is an off-by-one because maybe_script_execute fails to count
|
|
||||||
the terminating NULL when sizing new_argv.
|
|
||||||
|
|
||||||
ChangeLog:
|
|
||||||
|
|
||||||
* sysdeps/unix/sysv/linux/spawni.c (maybe_script_execute):
|
|
||||||
Increment size of new_argv by one.

Fix misreported errno on preadv2/pwritev2 (BZ#23579)
|
|
||||||
|
|
||||||
The fallback code of Linux wrapper for preadv2/pwritev2 executes
|
|
||||||
regardless of the errno code for preadv2, instead of the case where
|
|
||||||
the syscall is not supported.
|
|
||||||
|
|
||||||
This fixes it by calling the fallback code iff errno is ENOSYS. The
|
|
||||||
patch also adds tests for both invalid file descriptor and invalid
|
|
||||||
iov_len and vector count.
|
|
||||||
|
|
||||||
The only discrepancy between preadv2 and fallback code regarding
|
|
||||||
error reporting is when an invalid flags are used. The fallback code
|
|
||||||
bails out earlier with ENOTSUP instead of EINVAL/EBADF when the syscall
|
|
||||||
is used.
|
|
||||||
|
|
||||||
Checked on x86_64-linux-gnu on a 4.4.0 and 4.15.0 kernel.
|
|
||||||
|
|
||||||

i386: Use _dl_runtime_[resolve|profile]_shstk for SHSTK [BZ #23716]
|
|
||||||
|
|
||||||
When elf_machine_runtime_setup is called to set up resolver, it should
|
|
||||||
use _dl_runtime_resolve_shstk or _dl_runtime_profile_shstk if SHSTK is
|
|
||||||
enabled by kernel.
|
|
||||||
|
|
||||||
Tested on i686 with and without --enable-cet as well as on CET emulator
|
|
||||||
with --enable-cet.
|
|
||||||
|
|
||||||
[BZ #23716]
|
|
||||||
* sysdeps/i386/dl-cet.c: Removed.
|
|
||||||
* sysdeps/i386/dl-machine.h (_dl_runtime_resolve_shstk): New
|
|
||||||

|
|
||||||

|
|
||||||
(elf_machine_runtime_setup): Use _dl_runtime_profile_shstk or
|
|
||||||
_dl_runtime_resolve_shstk if SHSTK is enabled by kernel.

Fix race in pthread_mutex_lock while promoting to PTHREAD_MUTEX_ELISION_NP [BZ #23275]
|
|
||||||
|
|
||||||
The race leads either to pthread_mutex_destroy returning EBUSY
|
|
||||||
or triggering an assertion (See description in bugzilla).
|
|
||||||
|
|
||||||
This patch is fixing the race by ensuring that the elision path is
|
|
||||||
used in all cases if elision is enabled by the GLIBC_TUNABLES framework.
|
|
||||||
|
|
||||||
The __kind variable in struct __pthread_mutex_s is accessed concurrently.
|
|
||||||
Therefore we are now using the atomic macros.
|
|
||||||
|
|
||||||
The new testcase tst-mutex10 is triggering the race on s390x and intel.
|
|
||||||
Presumably also on power, but I don't have access to a power machine
|
|
||||||
with lock-elision. At least the code for power is the same as on the other
|
|
||||||
two architectures.
|
|
||||||
|
|
||||||

|
|
||||||

|

+ by using the macro FORCE_ELISION. This macro is only defined for
|

+ architectures which supports lock elision.
|
|
||||||
+
|
|
||||||
+ For elision, there are the flags PTHREAD_MUTEX_ELISION_NP and
|
|
||||||
+ PTHREAD_MUTEX_NO_ELISION_NP which can be set in addition to the already set
|
|
||||||
+ type of a mutex.
|
|
||||||
+ Before a mutex is initialized, only PTHREAD_MUTEX_NO_ELISION_NP can be set
|
|
||||||
+ with pthread_mutexattr_settype.
|
|
||||||
+ After a mutex has been initialized, the functions pthread_mutex_*lock can
|
|
||||||
+ enable elision - if the mutex-type and the machine supports it - by setting
|
|
||||||
+ the flag PTHREAD_MUTEX_ELISION_NP. This is done concurrently. Afterwards
|
|
||||||

malloc: Verify size of top chunk.
|
|
||||||
|
|
||||||
The House of Force is a well-known technique to exploit heap
|
|
||||||
overflow. In essence, this exploit takes three steps:
|
|
||||||
1. Overwrite the size of top chunk with very large value (e.g. -1).
|
|
||||||
2. Request x bytes from top chunk. As the size of top chunk
|
|
||||||
is corrupted, x can be arbitrarily large and top chunk will
|
|
||||||
still be offset by x.
|
|
||||||
3. The next allocation from top chunk will thus be controllable.
|
|
||||||
|
|
||||||
If we verify the size of top chunk at step 2, we can stop such attack.

I'm fairly certain that it compares mchunk_size of victim against
|
|
||||||
mchunk_prev_size of the next chunk, i.e. the size of victim in its
|
|
||||||
header and footer.

|
|

You are right, I don't think it makes a difference in these checks. So
|
|
||||||
the size local can be reused for the checks against victim. For next,
|
|
||||||
leaving it as such avoids the masking operation.

|
|
||||||
|
|
||||||
We could also do a chunk boundary check similar to what I proposed in
|
|
||||||
the thread for the first patch in the series to be even more strict.
|
|
||||||
I'll gladly try to implement either but believe that refining these
|
|
||||||
checks would bring less benefits than in the case of the top chunk.
|
|
||||||
Intra-arena or intra-heap overlaps would still be doable here with
|
|
||||||
unsorted chunks and I don't see any way to counter that besides more
|
|
||||||
generic measures like randomizing allocations and your metadata
|
|
||||||
encoding patches.
|
|
||||||
|
|
||||||
I've attached a revised version with the above comments incorporated
|
|
||||||
but without the refined checks.

||||||

I.
|
|

|
|

Ensure the following properties of chunks encountered during binning:
|

- victim chunk has reasonable size
|
|
||||||
- next chunk has reasonable size
|
|
||||||
- next->prev_size == victim->size
|
|
||||||
- valid double linked list
|
|
||||||
- PREV_INUSE of next chunk is unset

malloc: Check for large bin list corruption when inserting unsorted chunk
|
|
||||||
|
|
||||||
Fixes bug 24216. This patch adds security checks for bk and bk_nextsize pointers
|
|
||||||
of chunks in large bin when inserting chunk from unsorted bin. It was possible
|
|
||||||
to write the pointer to victim (newly inserted chunk) to arbitrary memory
|
|
||||||
locations if bk or bk_nextsize pointers of the next large bin chunk
|
|
||||||
got corrupted.

powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSC
|
|
||||||
|
|
||||||
Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls,
|
|
||||||
instead it suspend and resume it when leaving the kernel. The
|
|
||||||
side-effects of the syscall will always remain visible, even if the
|
|
||||||
transaction is aborted. This is an issue when transaction is used along
|
|
||||||
with futex syscall, on pthread_cond_wait for instance, where the futex
|
|
||||||
call might succeed but the transaction is rolled back leading the
|
|
||||||
pthread_cond object in an inconsistent state.
|
|
||||||
|
|
||||||
Glibc used to prevent it by always aborting a transaction before issuing
|
|
||||||
a syscall. Linux 4.2 also decided to abort active transaction in
|
|
||||||
syscalls which makes the glibc workaround superfluous. Worse, glibc
|
|
||||||
transaction abortion leads to a performance issue on recent kernels
|
|
||||||
where the HTM state is saved/restore lazily (v4.9). By aborting a
|
|
||||||
transaction on every syscalls, regardless whether a transaction has being
|
|
||||||
initiated before, GLIBS makes the kernel always save/restore HTM state
|
|
||||||
(it can not even lazily disable it after a certain number of syscall
|
|
||||||
iterations).
|
|
||||||
|
|
||||||
Because of this shortcoming, Transactional Lock Elision is just enabled
|
|
||||||
when it has been explicitly set (either by tunables of by a configure
|
|
||||||
switch) and if kernel aborts HTM transactions on syscalls
|
|
||||||
(PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1],
|
|
||||||
the context-switch is about 5% faster by not issuing a tabort in every
|
|
||||||
syscall in newer kernels.
|
|
||||||
|
|
||||||
Checked on powerpc64le-linux-gnu with 4.4.0 kernel (Ubuntu 16.04).

||||||
