Previous devices hardcoded the PCI Maximum Read Request Size to 4K. To better comply with the PCI spec, the hardware now defaults the MRRS to 512 bytes. This will yield poor driver performance if left untouched. This patch increases the MRRS to 4K on driver initialization.

5784 and 5764 devices fail to link / pass traffic after one load / unload cycle. This happens because of a hardware bug in the new CPMU. During normal operation, the MAC depends on the PHY clock being available. When the PHY is powered down, the clock the MAC depends on is disabled. The fix is to switch the MAC clock to an alternate source before powering down the PHY, and to restore the MAC clock to the PHY source upon device resume.

When 5761 devices boot the machine using PXEboot, PXE leaves the device active when it terminates. The tg3 driver has code to detect this condition and resets the device during initialization. On 5761 devices, device resets involve sending a driver state update message to the APE on the 5761. However, during this initialization stage, communications to the APE registers have not yet been set up. The driver then dereferences a NULL pointer and crashes the machine. The fix is to move the APE register access setup earlier in the initialization code to cover this condition.

...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers. Looking at the sock->op->shutdown() handlers, it looks as if all of them take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the RCV_SHUTDOWN/SEND_SHUTDOWN arguments.

Commit bea3348e (the NAPI changes) made sungem unconditionally enable NAPI when resuming and unconditionally disable when suspending, this, however, makes napi_disable() hang when suspending when the interface was taken down before suspend because taking the interface down also disables NAPI. This patch makes touching the napi struct in suspend/resume code paths depend on having the interface up, thereby fixing the hang on suspend. The patch also moves the napi_disable() in gem_close() under the lock so that the NAPI state is always modified atomically together with the "opened" variable.

While a signal is blocked, it must be posted even if its action is SIG_IGN or is SIG_DFL with the default action to ignore. This works right most of the time, but is broken when a sigwait (rt_sigtimedwait) is in progress. This changes the early-discard check to respect real_blocked. ~blocked is the set to check for "should wake up now", but ~(blocked|real_blocked) is the set for "blocked" semantics as defined by POSIX.

由 J. Bruce Fields 提交于
As with commit 7fc90ec9 ("knfsd: nfsd: call nfsd_setuser() on fh_compose(), fix nfsd4 permissions problem") this is a case where we need to redo a security check in fh_verify() even though the filehandle already has an associated dentry--if the filehandle was created by fh_compose() in an earlier operation of the nfsv4 compound, then we may not have done these checks yet. Without this fix it is possible, for example, to traverse from an export without the secure ports requirement to one with it in a single compound, and bypass the secure port check on the new export. While we're here, fix up some minor style problems and change a printk() to a dprintk(), to make it harder for random unprivileged users to spam the logs. Signed-off-by: NJ.

The v2/v3 acl code in nfsd is translating any return from fh_verify() to nfserr_inval. This is particularly unfortunate in the case of an nfserr_dropit return, which is an internal error meant to indicate to callers that this request has been deferred and should just be dropped pending the results of an upcall to mountd.

The coredump code always calls set_dumpable(0) when it starts (even if RLIMIT_CORE prevents any core from being dumped). The effect of this (via task_dumpable) is to make /proc/pid/* files owned by root instead of the user, so the user can no longer examine his own process--in a case where there was never any privileged data to protect. This affects e.g. auxv, environ, fd; in Fedora (execshield) kernels, also maps. In practice, you can only notice this when a debugger has requested PTRACE_EVENT_EXIT tracing. set_dumpable was only used in do_coredump for synchronization and not intended for any security purpose. (It doesn't secure anything that wasn't already unsecured when a process dies by SIGTERM instead of SIGQUIT.) This changes do_coredump to check the core_waiters count as the means of synchronization, which is sufficient. Now we leave the "dumpable" bits alone.

In net/sctp/sm_statefuns.c::sctp_sf_abort_violation() we may leak the storage allocated for 'abort' by returning from the function without using or freeing it. This happens in case "sctp_auth_recv_cid(SCTP_CID_ABORT, asoc)" is true and we jump to the 'discard' label. Spotted by the Coverity checker. The simple fix is to simply move the creation of the "abort chunk" to after the possible jump to the 'discard' label. This way we don't even have to allocate the memory at all in the problem case.

The virtio descriptor rings of size N-1 were nicely set up to be aligned to an N-byte boundary. But as Anthony Liguori points out, the free-running indices used by virtio require that the sizes be a power of 2, otherwise we get problems on wrap (demonstrated with lguest). So we replace the clever "2^n-1" scheme with a simple "align to page boundary" scheme: this means that all virtio rings take at least two pages, but it's safer than guessing cache alignment.

The more_used() function compares the vq->vring.used->idx with last_used_idx. Since vq->vring.used->idx is a 16-bit integer, and last_used_idx is an unsigned int, this results in unpredictable behavior when vq->vring.used->idx wraps around.
