This change ensures that the set*uid family of syscalls in kernel/sys.c (setreuid, setuid, setresuid, setfsuid) all call ns_capable_common with the CAP_OPT_INSETID flag, so capability checks in the security_capable hook can know whether they are being called from within a set*uid syscall. This change is a no-op by itself, but is needed for the proposed SafeSetID LSM. Signed-off-by:

GCC 9 reworks the way the references to the stack canary are emitted, to prevent the value from being spilled to the stack before the final comparison in the epilogue, defeating the purpose, given that the spill slot is under control of the attacker that we are protecting ourselves from. Since our canary value address is obtained without accessing memory (as opposed to pre-v7 code that will obtain it from a literal pool), it is unlikely (although not guaranteed) that the compiler will spill the canary value in the same way, so let's just disable this improvement when building with GCC9+.

If an input number x for int_sqrt64() has the highest bit set, then fls64(x) is 64. (1UL << 64) is an overflow and breaks the algorithm. Subtracting 1 is a better guess for the initial value of m anyway and that's what also done in int_sqrt() implicitly [*]. [*] Note how int_sqrt() uses __fls() with two underscores, which already returns the proper raw bit number. In contrast, int_sqrt64() used fls64(), and that returns bit numbers illogically starting at 1, because of error handling for the "no bits set" case. Will points out that he bug probably is due to a copy-and-paste error from the regular int_sqrt() case. Signed-off-by:

Commit 594cc251 ("make 'user_access_begin()' do 'access_ok()'") makes the access_ok() check part of the user_access_begin() preceding a series of 'unsafe' accesses. This has the desirable effect of ensuring that all 'unsafe' accesses have been range-checked, without having to pick through all of the callsites to verify whether the appropriate checking has been made. However, the consolidated range check does not inhibit speculation, so it is still up to the caller to ensure that they are not susceptible to any speculative side-channel attacks for user addresses that ultimately fail the access_ok() check. This is an oversight, so use __uaccess_begin_nospec() to ensure that speculation is inhibited until the access_ok() check has passed. Reported-by:

Redirecting to a sit0 through __bpf_redirect_no_mac pulls the mac length, even though skb->data already is at skb->network_header. bpf_prog_test_run_skb has already pulled it as LWT_XMIT !is_l2. Update the offset calculation to pull only if skb->data differs from skb->network_header, which is not true in this case. The test itself can be run only from commit 1cf1cae9 ("bpf: introduce BPF_PROG_TEST_RUN command"), but the same type of packets with skb at network header could already be built from lwt xmit hooks, so this fix is more relevant to that commit. Also set the mac header on redirect from LWT_XMIT, as even after this change to __bpf_redirect_no_mac that field is expected to be set, but is not yet in ip_finish_output2.

Commit 8ce5f841 ("of: Remove struct device_node.type pointer") removed struct device_node.type pointer, but the conversion to use of_node_is_type() accessor was missed in chrp_init_IRQ(). Fixes: 8ce5f841 ("of: Remove struct device_node.type pointer") Reported-by:

For -stable v4.18 ('net/mlx5e: Force CHECKSUM_UNNECESSARY for short ethernet frames') The patch doesn't apply cleanly to 4.18.y, but it is very simple to resolve, what should be the procedure here ? ==================== Signed-off-by:

Previously the identifier used for indirect block callback registry and for block rule cb registry (when done via indirect blocks) was the pointer to the tunnel netdev we were interested in receiving updates on. This worked fine if a single PF existed that registered one callback for the tunnel netdev of interest. However, if multiple PFs are in place then the 2nd PF tries to register with the same tunnel netdev identifier. This leads to EEXIST errors and/or incorrect cb deletions. Prevent this conflict by using the rpriv pointer as the identifier for netdev indirect block cb registry, allowing each PF to register a unique callback per tunnel netdev. For block cb registry, the same PF may register multiple cbs to the same block if using TC shared blocks. Instead of the rpriv, use the pointer to the allocated indr_priv data as the identifier here. This means that there can be a unique block callback for each PF/tunnel netdev combo. Fixes: f5bc2c5d ("net/mlx5e: Support TC indirect block notifications for eswitch uplink reprs") Signed-off-by:
