Subject: [PATCH] tc: f_flower: Add option to match on related ct state
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1957243
Upstream Status: unknown commit 7fda6c58
commit 7fda6c588a295ad381fdf0b9b9971169b2f9d9dc
Author: Ariel Levkovich <lariel@nvidia.com>
Date: Fri May 21 20:07:06 2021 +0300
tc: f_flower: Add option to match on related ct state
Add support for matching on ct_state flag related.
The related state indicates a packet is associated with an existing
connection.
Example:
$ tc filter add dev ens1f0_0 ingress prio 1 chain 1 proto ip flower \
ct_state -est-rel+trk \
action mirred egress redirect dev ens1f0_1
$ tc filter add dev ens1f0_0 ingress prio 1 chain 1 proto ip flower \
ct_state +rel+trk \
action mirred egress redirect dev ens1f0_1

Subject: [PATCH] m_vlan: add pop_eth and push_eth actions
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1885770
Upstream Status: unknown commit d61167dd
commit d61167dd88b45832843b1458cd156f3b85c8ff16
Author: Guillaume Nault <gnault@redhat.com>
Date: Mon Oct 19 17:23:01 2020 +0200
m_vlan: add pop_eth and push_eth actions
Add support for the new TCA_VLAN_ACT_POP_ETH and TCA_VLAN_ACT_PUSH_ETH
actions (kernel commit 19fbcb36a39e ("net/sched: act_vlan:
Add {POP,PUSH}_ETH actions"). These action let TC remove or add the
Ethernet at the head of a frame.
Drop an Ethernet header:
# tc filter add dev ethX matchall action vlan pop_eth
Push an Ethernet header (the original frame must have no MAC header):
# tc filter add dev ethX matchall action vlan \
push_eth dst_mac 0a:00:00:00:00:02 src_mac 0a:00:00:00:00:01
Also add a test suite for m_vlan, which covers these new actions and
the pre-existing ones.

+ *
+ * The *prog_fd* must be a valid file descriptor associated with
+ * a loaded eBPF program of type **BPF_PROG_TYPE_RAW_TRACEPOINT**.
+ *
+ * No ABI guarantees are made about the content of tracepoint

+ *
+ * The returned file descriptor can be passed to other **bpf**\ ()
+ * subcommands such as **BPF_PROG_LOAD** or **BPF_MAP_CREATE** to
+ * associate the BTF with those objects.
+ *
+ * Similar to **BPF_PROG_LOAD**, **BPF_BTF_LOAD** has optional

+ * error occurred (in which case, *errno* is set appropriately).
+ *
+ * BPF_TASK_FD_QUERY
+ * Description
+ * Obtain information about eBPF programs associated with the
+ * target process identified by *pid* and *fd*.
+ *
+ * If the *pid* and *fd* are associated with a tracepoint, kprobe
+ * or uprobe perf event, then the *prog_id* and *fd_type* will
+ * be populated with the eBPF program id and file descriptor type
+ * of type **bpf_task_fd_type**. If associated with a kprobe or

+ * populated. Optionally, if *buf* is provided, then up to
+ * *buf_len* bytes of *buf* will be populated with the name of
+ * the tracepoint, kprobe or uprobe.
+ *
+ * The resulting *prog_id* may be introspected in deeper detail
+ * using **BPF_PROG_GET_FD_BY_ID** and **BPF_OBJ_GET_INFO_BY_FD**.

+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_MAP_LOOKUP_AND_DELETE_ELEM
+ * Description
+ * Look up an element with the given *key* in the map referred to
+ * by the file descriptor *fd*, and if found, delete the element.
+ *
+ * The **BPF_MAP_TYPE_QUEUE** and **BPF_MAP_TYPE_STACK** map types
+ * implement this command as a "pop" operation, deleting the top
+ * element rather than one corresponding to *key*.
+ * The *key* and *key_len* parameters should be zeroed when
+ * issuing this operation for these map types.
+ *
+ * This command is only valid for the following map types:
+ * * **BPF_MAP_TYPE_QUEUE**
+ * * **BPF_MAP_TYPE_STACK**
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_MAP_FREEZE
+ * Description
+ * Freeze the permissions of the specified map.
+ *
+ * Write permissions may be frozen by passing zero *flags*.
+ * Upon success, no future syscall invocations may alter the
+ * map state of *map_fd*. Write operations from eBPF programs
+ * are still possible for a frozen map.
+ *
+ * Not supported for maps of type **BPF_MAP_TYPE_STRUCT_OPS**.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_BTF_GET_NEXT_ID
+ * Description
+ * Fetch the next BPF Type Format (BTF) object currently loaded
+ * into the kernel.
+ *
+ * Looks for the BTF object with an id greater than *start_id*
+ * and updates *next_id* on success. If no other BTF objects
+ * remain with ids higher than *start_id*, returns -1 and sets
+ * *errno* to **ENOENT**.
+ *
+ * Return
+ * Returns zero on success. On error, or when no id remains, -1
+ * is returned and *errno* is set appropriately.
+ *
+ * BPF_MAP_LOOKUP_BATCH
+ * Description
+ * Iterate and fetch multiple elements in a map.
+ *
+ * Two opaque values are used to manage batch operations,
+ * *in_batch* and *out_batch*. Initially, *in_batch* must be set
+ * to NULL to begin the batched operation. After each subsequent
+ * **BPF_MAP_LOOKUP_BATCH**, the caller should pass the resultant
+ * *out_batch* as the *in_batch* for the next operation to
+ * continue iteration from the current point.
+ *
+ * The *keys* and *values* are output parameters which must point
+ * to memory large enough to hold *count* items based on the key
+ * and value size of the map *map_fd*. The *keys* buffer must be
+ * of *key_size* * *count*. The *values* buffer must be of
+ * *value_size* * *count*.
+ *
+ * The *elem_flags* argument may be specified as one of the
+ * following:
+ *
+ * **BPF_F_LOCK**
+ * Look up the value of a spin-locked map without
+ * returning the lock. This must be specified if the
+ * elements contain a spinlock.
+ *
+ * On success, *count* elements from the map are copied into the
+ * user buffer, with the keys copied into *keys* and the values
+ * copied into the corresponding indices in *values*.
+ *
+ * If an error is returned and *errno* is not **EFAULT**, *count*
+ * is set to the number of successfully processed elements.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * May set *errno* to **ENOSPC** to indicate that *keys* or
+ * *values* is too small to dump an entire bucket during
+ * iteration of a hash-based map type.
+ *
+ * BPF_MAP_LOOKUP_AND_DELETE_BATCH
+ * Description
+ * Iterate and delete all elements in a map.
+ *
+ * This operation has the same behavior as
+ * **BPF_MAP_LOOKUP_BATCH** with two exceptions:
+ *
+ * * Every element that is successfully returned is also deleted
+ * from the map. This is at least *count* elements. Note that
+ * *count* is both an input and an output parameter.
+ * * Upon returning with *errno* set to **EFAULT**, up to
+ * *count* elements may be deleted without returning the keys
+ * and values of the deleted elements.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_MAP_UPDATE_BATCH
+ * Description
+ * Update multiple elements in a map by *key*.
+ *
+ * The *keys* and *values* are input parameters which must point
+ * to memory large enough to hold *count* items based on the key
+ * and value size of the map *map_fd*. The *keys* buffer must be
+ * of *key_size* * *count*. The *values* buffer must be of
+ * *value_size* * *count*.
+ *
+ * Each element specified in *keys* is sequentially updated to the
+ * value in the corresponding index in *values*. The *in_batch*
+ * and *out_batch* parameters are ignored and should be zeroed.
+ *
+ * The *elem_flags* argument should be specified as one of the
+ * following:
+ *
+ * **BPF_ANY**
+ * Create new elements or update a existing elements.
+ * **BPF_NOEXIST**
+ * Create new elements only if they do not exist.
+ * **BPF_EXIST**
+ * Update existing elements.
+ * **BPF_F_LOCK**
+ * Update spin_lock-ed map elements. This must be
+ * specified if the map value contains a spinlock.
+ *
+ * On success, *count* elements from the map are updated.
+ *
+ * If an error is returned and *errno* is not **EFAULT**, *count*
+ * is set to the number of successfully processed elements.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * May set *errno* to **EINVAL**, **EPERM**, **ENOMEM**, or
+ * **E2BIG**. **E2BIG** indicates that the number of elements in
+ * the map reached the *max_entries* limit specified at map
+ * creation time.
+ *
+ * May set *errno* to one of the following error codes under
+ * specific circumstances:
+ *
+ * **EEXIST**
+ * If *flags* specifies **BPF_NOEXIST** and the element
+ * with *key* already exists in the map.
+ * **ENOENT**
+ * If *flags* specifies **BPF_EXIST** and the element with
+ * *key* does not exist in the map.
+ *
+ * BPF_MAP_DELETE_BATCH
+ * Description
+ * Delete multiple elements in a map by *key*.
+ *
+ * The *keys* parameter is an input parameter which must point
+ * to memory large enough to hold *count* items based on the key
+ * size of the map *map_fd*, that is, *key_size* * *count*.
+ *
+ * Each element specified in *keys* is sequentially deleted. The
+ * *in_batch*, *out_batch*, and *values* parameters are ignored
+ * and should be zeroed.
+ *
+ * The *elem_flags* argument may be specified as one of the
+ * following:
+ *
+ * **BPF_F_LOCK**
+ * Look up the value of a spin-locked map without
+ * returning the lock. This must be specified if the
+ * elements contain a spinlock.
+ *
+ * On success, *count* elements from the map are updated.
+ *
+ * If an error is returned and *errno* is not **EFAULT**, *count*
+ * is set to the number of successfully processed elements. If
+ * *errno* is **EFAULT**, up to *count* elements may be been
+ * deleted.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_LINK_CREATE
+ * Description
+ * Attach an eBPF program to a *target_fd* at the specified
+ * *attach_type* hook and return a file descriptor handle for
+ * managing the link.
+ *
+ * Return
+ * A new file descriptor (a nonnegative integer), or -1 if an
+ * error occurred (in which case, *errno* is set appropriately).

+ *
+ * BPF_LINK_GET_NEXT_ID
+ * Description
+ * Fetch the next eBPF link currently loaded into the kernel.
+ *
+ * Looks for the eBPF link with an id greater than *start_id*
+ * and updates *next_id* on success. If no other eBPF links
+ * remain with ids higher than *start_id*, returns -1 and sets
+ * *errno* to **ENOENT**.
+ *
+ * Return
+ * Returns zero on success. On error, or when no id remains, -1
+ * is returned and *errno* is set appropriately.
+ *
+ * BPF_ENABLE_STATS
+ * Description
+ * Enable eBPF runtime statistics gathering.
+ *
+ * Runtime statistics gathering for the eBPF runtime is disabled
+ * by default to minimize the corresponding performance overhead.
+ * This command enables statistics globally.
+ *
+ * Multiple programs may independently enable statistics.
+ * After gathering the desired statistics, eBPF runtime statistics
+ * may be disabled again by calling **close**\ (2) for the file
+ * descriptor returned by this function. Statistics will only be
+ * disabled system-wide when all outstanding file descriptors
+ * returned by prior calls for this subcommand are closed.
+ *
+ * Return
+ * A new file descriptor (a nonnegative integer), or -1 if an
+ * error occurred (in which case, *errno* is set appropriately).

+ * file descriptor that can be used to trigger the iteration.
+ *
+ * If the resulting file descriptor is pinned to the filesystem
+ * using **BPF_OBJ_PIN**, then subsequent **read**\ (2) syscalls
+ * for that path will trigger the iterator to read kernel state
+ * using the eBPF program attached to *link_fd*.
+ *
+ * Return
+ * A new file descriptor (a nonnegative integer), or -1 if an
+ * error occurred (in which case, *errno* is set appropriately).
+ *
+ * BPF_LINK_DETACH
+ * Description
+ * Forcefully detach the specified *link_fd* from its
+ * corresponding attachment point.
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * BPF_PROG_BIND_MAP
+ * Description
+ * Bind a map to the lifetime of an eBPF program.
+ *
+ * The map identified by *map_fd* is bound to the program
+ * identified by *prog_fd* and only released when *prog_fd* is
+ * released. This may be used in cases where metadata should be
+ * associated with a program which otherwise does not contain any
+ * references to the map (for example, embedded in the eBPF
+ * program instructions).
+ *
+ * Return
+ * Returns zero on success. On error, -1 is returned and *errno*
+ * is set appropriately.
+ *
+ * NOTES
+ * eBPF objects (maps and programs) can be shared between processes.
+ *
+ * * After **fork**\ (2), the child inherits file descriptors
+ * referring to the same eBPF objects.
+ * * File descriptors referring to eBPF objects can be transferred over
+ * **unix**\ (7) domain sockets.
+ * * File descriptors referring to eBPF objects can be duplicated in the
+ * usual way, using **dup**\ (2) and similar calls.
+ * * File descriptors referring to eBPF objects can be pinned to the
+ * filesystem using the **BPF_OBJ_PIN** command of **bpf**\ (2).
+ *
+ * An eBPF object is deallocated only after all file descriptors referring
+ * to the object have been closed and no references remain pinned to the
+ * filesystem or attached (for example, bound to a program or device).

Subject: [PATCH] m_mpls: add mac_push action
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1885770
Upstream Status: unknown commit 02a261b5
commit 02a261b5ba1c8580ac2a35bc6c87faa2ec9f5c96
Author: Guillaume Nault <gnault@redhat.com>
Date: Mon Oct 19 17:23:08 2020 +0200
m_mpls: add mac_push action
Add support for the new TCA_MPLS_ACT_MAC_PUSH action (kernel commit
a45294af9e96 ("net/sched: act_mpls: Add action to push MPLS LSE before
Ethernet header")). This action let TC push an MPLS header before the
MAC header of a frame.
Example (encapsulate all outgoing frames with label 20, then add an
outer Ethernet header):
# tc filter add dev ethX matchall \
action mpls mac_push label 20 ttl 64 \
action vlan push_eth dst_mac 0a:00:00:00:00:02 \
src_mac 0a:00:00:00:00:01
This patch also adds an alias for ETH_P_TEB, since it is useful when
decapsulating MPLS packets that contain an Ethernet frame.
With MAC_PUSH, there's no previous Ethertype to modify. However, the
"protocol" option is still needed, because the kernel uses it to set
skb->protocol. So rename can_modify_ethtype() to can_set_ethtype().
Also add a test suite for m_mpls, which covers the new action and the
pre-existing ones.

Subject: [PATCH] m_mpls: test the 'mac_push' action after 'modify'
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1885770
Upstream Status: unknown commit f1298d76
commit f1298d76606a581cf3ab9ec45a92b41e72a6b4f0
Author: Guillaume Nault <gnault@redhat.com>

m_mpls: test the 'mac_push' action after 'modify'
Commit 02a261b5ba1c ("m_mpls: add mac_push action") added a matches()
test for the "mac_push" string before the test for "modify".
This changes the previous behaviour as 'action m' used to match
"modify" while it now matches "mac_push".
Revert to the original behaviour by moving the "mac_push" test after
"modify".
Fixes: 02a261b5ba1c ("m_mpls: add mac_push action")

police: add support for packet-per-second rate limiting
Allow a policer action to enforce a rate-limit based on packets-per-second,
configurable using a packet-per-second rate and burst parameters.
e.g.
# $TC actions add action police pkts_rate 1000 pkts_burst 200 index 1
# $TC actions ls action police
total acts 1
action order 0: police 0x1 rate 0bit burst 0b mtu 4096Mb pkts_rate 1000 pkts_burst 200

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1885770
Upstream Status: unknown commit 8682f588
commit 8682f588bfed7862233a22626562696d662ca60c
Author: Guillaume Nault <gnault@redhat.com>

tc-mpls: fix manpage example and help message string
Manpage:
* Remove the extra "and to ip packets" part from command description
to make it more understandable.
* Redirect packets to eth1, instead of eth0, as told in the
description.
Help string:
* "mpls pop" can be followed by a CONTROL keyword.
* "mpls modify" can also set the MPLS_BOS field.

Upstream Status: unknown commit 676a1a70
commit 676a1a708f8e99d6a4faa3de8a093f8f8c14b9da
Author: Guillaume Nault <gnault@redhat.com>

tc: flower: fix json output with mpls lse
The json output of the TCA_FLOWER_KEY_MPLS_OPTS attribute was invalid.
Example:
$ tc filter add dev eth0 ingress protocol mpls_uc flower mpls \
lse depth 1 label 100 \
lse depth 2 label 200
$ tc -json filter show dev eth0 ingress
...{"eth_type":"8847",
" mpls":[" lse":["depth":1,"label":100],
" lse":["depth":2,"label":200]]}...
This is invalid as the arrays, introduced by "[", can't contain raw
string:value pairs. Those must be enclosed into "{}" to form valid json
ojects. Also, there are spurious whitespaces before the mpls and lse
strings because of the indentation used for normal output.
Fix this by putting all LSE parameters (depth, label, tc, bos and ttl)
into the same json object. The "mpls" key now directly contains a list
of such objects.
Also, handle strings differently for normal and json output, so that
json strings don't get spurious indentation whitespaces.
Normal output isn't modified.
The json output now looks like:
$ tc -json filter show dev eth0 ingress
...{"eth_type":"8847",
"mpls":[{"depth":1,"label":100},
{"depth":2,"label":200}]}...

tc: u32: Fix key folding in sample option
In between Linux kernel 2.4 and 2.6, key folding for hash tables changed
in kernel space. When iproute2 dropped support for the older algorithm,
the wrong code was removed and kernel 2.4 folding method remained in
place. To get things functional for recent kernels again, restoring the
old code alone was not sufficient - additional byteorder fixes were
needed.
While being at it, make use of ffs() and thereby align the code with how
kernel determines the shift width.
Fixes: 267480f55383c ("Backout the 2.4 utsname hash patch.")

iproute: force rtm_dst_len to 32/128
Since NETLINK_GET_STRICT_CHK was enabled, the kernel rejects commands
that pass a prefix length, eg:
ip route get `1.0.0.0/1
Error: ipv4: Invalid values in header for route get request.
ip route get 0.0.0.0/0
Error: ipv4: rtm_src_len and rtm_dst_len must be 32 for IPv4
Since there's no point in setting a rtm_dst_len that we know is going
to be rejected, just force it to the right value if it's passed on
the command line. Print a warning to stderr to notify users.

commit e44786b26934e4fbf337b0af73a9e6f53d458a25

tc: htb: improve burst error messages
When a wrong value is provided for "burst" or "cburst" parameters, the
resulting error message is unclear and can be misleading:
$ tc class add dev dummy0 parent 1: classid 1:1 htb rate 100KBps burst errtrigger
Illegal "buffer"
The message claims an illegal "buffer" is provided, but neither the
inline help nor the man page list "buffer" among the htb parameters, and
the only way to know that "burst", "maxburst" and "buffer" are synonyms
is to look into tc/q_htb.c.
This commit tries to improve this simply changing the error string to
the parameter name provided in the user-given command, clearly pointing
out where the wrong value is.
$ tc class add dev dummy0 parent 1: classid 1:1 htb rate 100KBps burst errtrigger
Illegal "burst"
$ tc class add dev dummy0 parent 1: classid 1:1 htb rate 100Kbps maxburst errtrigger
Illegal "maxburst"

* Remove SRCPORTMIN description from help message since it doesn't
appear in the syntax string.
* Use same keywords in help message and in man page.
* Use the "ethertype" option name (.B ethertype) rather than the
option value (.I ETHERTYPE) in the man page description of
[no]multiproto.

Upstream Status: iproute2.git commit 2f5825cb
commit 2f5825cb38028a14961a79844a069be4e3057eca
Author: Andrea Claudi <aclaudi@redhat.com>
Date: Tue Sep 21 11:33:24 2021 +0200
lib: bpf_legacy: fix bpffs mount when /sys/fs/bpf exists
bpf selftests using iproute2 fails with:
$ ip link set dev veth0 xdp object ../bpf/xdp_dummy.o section xdp_dummy
Continuing without mounted eBPF fs. Too old kernel?
mkdir (null)/globals failed: No such file or directory
Unable to load program
This happens when the /sys/fs/bpf directory exists. In this case, mkdir
in bpf_mnt_check_target() fails with errno == EEXIST, and the function
returns -1. Thus bpf_get_work_dir() does not call bpf_mnt_fs() and the
bpffs is not mounted.
Fix this in bpf_mnt_check_target(), returning 0 when the mountpoint
exists.
Fixes: d4fcdbbec9df ("lib/bpf: Fix and simplify bpf_mnt_check_target()")
