This bug was caught by LTP testcase fchmod06 on Blackfin platform. In the manpage of fchmod, "EPERM: The effective UID does not match the owner of the file, and the process is not privileged (Linux: it does not have the CAP_FOWNER capability)." But the ramfs nommu code missed the inode_change_ok POSIX UID/GID verification. This patch fixed this.

This is a minor fix, but what is currently there is essentially wrong. In do_page_fault, if the faulting address from user code happens to be in kernel address space (int *p = (int*)-1; p = 0xbed;) then the do_page_fault handler will jump over the local_irq_enable with the goto bad_area_nosemaphore; But the first line there sees this is user code and goes through the process of sending a signal to send SIGSEGV to the user task. This whole time interrupts are disabled and the task can not be preempted by a higher priority task. This patch always enables interrupts in the user path of the bad_area_nosemaphore.

We used to access the 64-bit IRQ IMAP and ICLR registers of bus controllers 4-bytes in and as a 32-bit register word, since only the low 32-bits were relevant. This seemed like a good idea at the time. But the PCI-E controller requires full 8-byte 64-bit access to these registers, so we switched over to accessing them fully. SBUS was not adjusted properly, which broke interrupts completely. Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Currently we check for permission before deleting entries from SAD and SPD, (see security_xfrm_policy_delete() security_xfrm_state_delete()) However we are not checking for authorization when flushing the SPD and the SAD completely. It was perhaps missed in the original security hooks patch. This patch adds a security check when flushing entries from the SAD and SPD. It runs the entire database and checks each entry for a denial. If the process attempting the flush is unable to remove all of the entries a denial is logged the the flush function returns an error without removing anything. This is particularly useful when a process may need to create or delete its own xfrm entries used for things like labeled networking but that same process should not be able to delete other entries or flush the entire database.

由 Miklos Szeredi 提交于
A recv() on an AF_UNIX, SOCK_STREAM socket can race with a send()+close() on the peer, causing recv() to return zero, even though the sent data should be received. This happens if the send() and the close() is performed between skb_dequeue() and checking sk->sk_shutdown in unix_stream_recvmsg(): process A skb_dequeue() returns NULL, there's no data in the socket queue process B new data is inserted onto the queue by unix_stream_sendmsg() process B sk->sk_shutdown is set to SHUTDOWN_MASK by unix_release_sock() process A sk->sk_shutdown is checked, unix_release_sock() returns zero I'm surprised nobody noticed this, it's not hard to trigger. Maybe it's just (un)luck with the timing. It's possible to work around this bug in userspace, by retrying the recv() once in case of a zero return value.

由 Dmitry Mishin 提交于
check_compat_entry_size_and_hooks iterates over the matches and calls compat_check_calc_match, which loads the match and calculates the compat offsets, but unlike the non-compat version, doesn't call ->checkentry yet. On error however it calls cleanup_matches, which in turn calls ->destroy, which can result in crashes if the destroy function (validly) expects to only get called after the checkentry function. Add a compat_release_match function that only drops the module reference on error and rename compat_check_calc_match to compat_find_calc_match to reflect the fact that it doesn't call the checkentry function.

When a helper module is unloaded all conntracks refering to it have their helper pointer NULLed out, leading to lots of races. In most places this can be fixed by proper use of RCU (they do already check for != NULL, but in a racy way), additionally nf_conntrack_expect_related needs to bail out when no helper is present. Also remove two paranoid BUG_ONs in nf_conntrack_proto_gre that are racy and not worth fixing. Signed-off-by: NPatrick McHarrdy <kaber@trash.net> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Previously inet devices were only constructed when addresses are added (or rarely in ipmr). Therefore the default config values they get are the ones at the time of these operations. Now that we're creating inet devices earlier, this changes the behaviour of default config values in an incompatible way (see bug #8519). This patch creates a compromise by setting the default values at the same point as before but only for those that have not been explicitly set by the user since the inet device's creation.

Previously once inetdev_init has been called on a device any changes made to ipv4_devconf_dflt would have no effect on that device's configuration. This creates a problem since we have moved the point where inetdev_init is called from when an address is added to where the device is registered. This patch is the first half of a set that tries to mimic the old behaviour while still calling inetdev_init. It propagates any changes to ipv4_devconf_dflt to those devices that have not had the corresponding attribute set. The next patch will forcibly set all values at the point where inetdev_init was previously called. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

The statistics block DMA on 5708 can be messed up occasionally on the average of about once per hour. If the user is reading the counters within one second after the corruption, the counters will be all messed up. One second later, the counters will be ok again until the next corruption occurs. The workaround is to disable the periodic statistics DMA. Instead, we manually trigger the DMA once a second in bnx2_timer(). This manual trigger of the DMA avoids the problem. As a consequence, we can only allow 0 or 1 second settings for ethtool -C statistics block. Thanks to Jean-Daniel Pauget <jd@disjunkt.com> and CaT <cat@zip.com.au> for reporting this rare problem.
