[PATCH v3 6/6] ima: Reset IMA_NONACTION_RULE_FLAGS after post_setattr

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> Commit 11c60f23ed13 ("integrity: Remove unused macro IMA_ACTION_RULE_FLAGS") removed the IMA_ACTION_RULE_FLAGS mask, due to it not being used after commit 0d73a55208e9 ("ima: re-introduce own integrity cache lock"). However, it seems that the latter commit mistakenly used the wrong mask when moving the code from ima_inode_post_setattr() to process_measurement(). There is no mention in the commit message about this change and it looks quite important, since changing from IMA_ACTIONS_FLAGS (later renamed to IMA_NONACTION_FLAGS) to IMA_ACTION_RULE_FLAGS was done by commit 42a4c603198f0 ("ima: fix ima_inode_post_setattr"). Restore the original change of resetting only the policy-specific flags and not the new file status, but with new mask 0xfb000000 since the policy-specific flags changed meanwhile. Also rename IMA_ACTION_RULE_FLAGS to IMA_NONACTION_RULE_FLAGS, to be consistent with IMA_NONACTION_FLAGS.

Re: TCP Fast Retransmission Issue

Hello Christian, It will cause problems for real applications if the specific event happens, but that happens with a very low probability.

Some packets sent during the high RTT phase experienced long delays in reaching the destination, while later packets, benefiting from the lower RTT, arrived earlier. This out-of-order arrival triggered the receiver to generate duplicate acknowledgments (dup ACKs). Due to the low RTT, these dup ACKs quickly reached the sender. Upon receiving three dup ACKs, the sender initiated a fast retransmission for an earlier packet that was not lost but was simply taking longer to arrive. Interestingly, despite the fast-retransmitted packet experienced a lower RTT, the original delayed packet still arrived first. When the receiver received this packet, it sent an ACK for the next packet in sequence. However, upon later receiving the fast-retransmitted packet, an issue arose in its logic for updating the acknowledgment number. As a result, even after the next expected packet was received, the acknowledgment number was not updated correctly. The receiver continued sending dup ACKs, ultimately forcing bbr into the retransmission timeout (RTO) phase. > > > > I generated this issue in linux kernel version 5.15.0-117-generic with Ubuntu 20.04. I attempted to confirm whether the issue persists with the latest Linux kernel. However, I discovered that the behavior of bbr has changed in the most recent kernel version, where it now sends chunks of packets instead of sending them one by one over time. As a result, I was unable to reproduce the specific sequence of events that triggered the bug we identified. Consequently, I could not confirm whether the bug still exists in the latest kernel. > > > > I believe that the issue (if still exists) will have to be resolved in the location net/ipv4/tcp_input.c or something like that.

[PATCH] net/sctp: Prevent autoclose integer overflow in sctp_association_init()

While by default max_autoclose equals to INT_MAX / HZ, one may set net.sctp.max_autoclose to UINT_MAX. There is code in sctp_association_init() that can consequently trigger overflow.

[PATCH v2] seccomp: passthrough uretprobe systemcall without filtering

by Eyal Birger

When attaching uretprobes to processes running inside docker, the attached process is segfaulted when encountering the retprobe. The reason is that now that uretprobe is a system call the default seccomp filters in docker block it as they only allow a specific set of known syscalls. This is true for other userspace applications which use seccomp to control their syscall surface. Since uretprobe is a "kernel implementation detail" system call which is not used by userspace application code directly, it is impractical and there's very little point in forcing all userspace applications to explicitly allow it in order to avoid crashing tracked processes. Pass this systemcall through seccomp without depending on configuration. Note: uretprobe isn't supported in i386 and __NR_ia32_rt_tgsigqueueinfo uses the same number as __NR_uretprobe so the syscall isn't forced in the compat bitmap.

[PATCH V2] USB: pci-quirks: Fix HCCPARAMS register error for LS7A EHCI

LS7A EHCI controller doesn't have extended capabilities, so the EECP (EHCI Extended Capabilities Pointer) field of HCCPARAMS register should be 0x0, but it reads as 0xa0 now.
