From 9aada05f4c7f95220a5b16416f530419db6b4dff Mon Sep 17 00:00:00 2001
From: "Dmitry V. Levin" <ldv@strace.io>
Date: Fri, 23 Jul 2021 08:00:00 +0000
Subject: [PATCH] tests: change sockopt-timestamp test to use
syscall(__NR_recvmsg)
Since the glibc recvmsg wrapper became unsuitable for our needs,
invoke __NR_recvmsg syscall directly.
* tests/sockopt-timestamp.c: Include "scno.h" and <errno.h>,
conditionalize on __NR_recvmsg.
(TEST_OLD_SCM_TIMESTAMPS): Remove.
(k_recvmsg): New function.
(test_sockopt): Use it instead of recvmsg.

Subject: [PATCH 147/150] filter_qualify: free allocated data on the error path
exit of parse_poke_token
While not terribly required due to the fact that issues with option
parsing lead to program termination, these changes avoid leaking data
allocated in the function's scope and not stored elsewhere, which might
come handy if it ever be used dynamically during the runtime.
This also has been reported as resource leaks by covscan, and these
changes should calm it.
* src/filter_qualify.c (parse_poke_token): Go to err label instead of
returning right away; free poke->data, poke, and str_tokenized before
returning false.

Subject: [PATCH 148/150] macros: expand BIT macros, add MASK macros; add
*_SAFE macros
These macros might make reading a code that often converts between powers
of 2 and values/masks a bit easier; moreover, the *_SAFE versions should
help in cases where the shift values are expected to be equal to the type
bit width (which lead to UB otherwise).
Switching from BIT to BIT32 should also clarify bitness, which may be somewhat
murky at times (cf. printxval, printflags, and printxvals).
* src/macros.h [!BIT] (BIT): Rename to...
[!BIT32] (BIT32): ...this.
[!BIT64] (BIT64): New macro.
[!MASK32] (MASK32): Likewise.
[!MASK64] (MASK64): Likewise.
(BIT32_SAFE, BIT64_SAFE, MASK32_SAFE, MASK64_SAFE): New macros.
(FLAG): Use BIT32.

Subject: [PATCH 149/150] trie: use BIT* and MASK* macros
This makes reading the code a bit easier. It also solves some issues
where there is a hypothertical possibility of having bit shifts of size
64, by virtue of using the *_SAFE macros (that should silence some
reported "left shifting by more than 63 bits has undefined behavior"
covscan issues).
* src/trie.c (trie_create): Use BIT32, MASK64.
(trie_create_data_block): Use BIT32, change iterator variable type
to size_t.
(trie_get_node): Use BIT64, MASK64.
(trie_data_block_calc_pos): Use BIT32, MASK64, MASK64_SAFE.
(trie_iterate_keys_node): Use BIT64, MASK64, MASK64_SAFE.
(trie_free_node): Use BIT64.

Subject: [PATCH 150/150] tee: rewrite num_params access in tee_fetch_buf_data
Pointer to num_params field of the fetched structure is passed in a
separate function argument which provokes covscan complaints about
uninitialised accesses and also tingles my aliasing rules senses.
Rewrite to access it via the arg_struct argument which is fetched
earlier in the function flow.
* src/tee.c (TEE_FETCH_BUF_DATA): Change &arg_.num_params
to offsetof(typeof(arg_), num_params).
(tee_fetch_buf_data): Accept offset of the num_params field instead
of pointer to it; reconstruct the num_params pointer using it.

Subject: [PATCH] tests: call setsockopt directly in sockopt-timestamp
While commit v5.13-10-g0211fdc "tests: change sockopt-timestamp test to
use syscall(__NR_recvmsg)" has fixed issues with glibc-induced mangling
on newer kernels, the combination of an older kernel and new glibc still
causes issues, as glibc silently falls back to SO_TIMESTAMP{,NS}_OLD, as
implemented in glibc-2.34~294 "linux: Add fallback for 64-bit time_t
SO_TIMESTAMP{NS}". Avoid that by calling setsockopt directly as well.
* tests/sockopt-timestamp.c (SC_setsockopt): New macro constant.
(k_setsockopt): New function.
(test_sockopt): Call k_setsockopt instead of setsockopt.
Complements: v5.13-10-g0211fdc "tests: change sockopt-timestamp test to use syscall(__NR_recvmsg)"

%description
The strace program intercepts and records the system calls called and
received by a running process. Strace can print a record of each
system call, its arguments and its return value. Strace is useful for
diagnosing problems and debugging, as well as for instructional
purposes.
Install strace if you need a tool to track the system calls made and
received by a process.
