When (de)configuring a vlan interface, the IFF_ALLMULTI ans IFF_PROMISC flags are cleared or set on the underlying interface. So, if these flags are changed on a vlan interface that is not up, the flags underlying interface might be set or cleared twice. Only propagating flag changes when a device is up makes sure this does not happen. It also makes sure that an underlying device is not set to promiscuous or allmulti mode for a vlan device that is down. Signed-off-by:

Whatever situations make this state legitimate when SMP also would be legitimate when !SMP and f.e. preemption is enabled. This is dubious enough that we should just delete it entirely. If we want to add debugging for neigh timer races, better more thorough mechanisms are needed. Signed-off-by: -

commit f1585086 (netfilter: nfnetlink_queue: return error number to caller) erronously assigns the return value of nf_queue() to the "ret" value. This can cause bogus return values if we encounter QUEUE verdict when bypassing is enabled, the listener does not exist and the next hook returns NF_STOLEN. In this case nf_hook_slow returned -ESRCH instead of 0. Signed-off-by:

Several callers (h323 conntrack, xt_addrtype) assume that the returned **dst only needs to be released if the function returns 0. This is true for the ipv4 implementation, but not for the ipv6 one. Instead of changing the users, change the ipv6 implementation to behave like the ipv4 version by only providing the dst_entry result in the success case. Signed-off-by:

This patch exports several definitions that used to live under include/net/netfilter/nf_nat.h. These definitions, although not exported, have been used by iptables and other userspace applications like miniupnpd since long time. Basically, these userspace tools included some internal definition of the required structures and they assume no changes in the binary representation (which is OK indeed). To resolve this situation, this patch makes public the required structure and install them in INSTALL_HDR_PATH. See: https://bugs.gentoo.org/376873, for more information. This patch is heavily based on the initial patch sent by: Anthony G. Basile <blueness@gentoo.org> Which was entitled: netfilter: export sanitized nf_nat.h to INSTALL_HDR_PATH Signed-off-by:

epoll can acquire recursively acquire ep->mtx on multiple "struct eventpoll"s at once in the case where one epoll fd is monitoring another epoll fd. This is perfectly OK, since we're careful about the lock ordering, but it causes spurious lockdep warnings. Annotate the recursion using mutex_lock_nested, and add a comment explaining the nesting rules for good measure. Recent versions of systemd are triggering this, and it can also be demonstrated with the following trivial test program: --------------------8<-------------------- int main(void) { int e1, e2; struct epoll_event evt = { .events = EPOLLIN }; e1 = epoll_create1(0); e2 = epoll_create1(0); epoll_ctl(e1, EPOLL_CTL_ADD, e2, &evt); return 0; } --------------------8<-------------------- Reported-by:Paul Bolle <pebolle@tiscali.nl> Tested-by:

Some find using utf-8 in commit logs inappropriate. Some patch commit logs contain unintended utf-8 characters when doing things like copy/pasting compilation output. Look for the start of any commit log by skipping initial lines that look like email headers and "From: " lines. Stop looking for utf-8 at the first signature line. Signed-off-by:

Commit 84c95c9a ("string: on strstrip(), first remove leading spaces before running over str") improved the performance of the strim() function. Unfortunately this changed the semantics of strim() and broke my code. Before the patch it was possible to use strim() without using the return value for removing trailing spaces from strings that had either only blanks or only trailing blanks. Now this does not work any longer for strings that *only* have blanks. Before patch: " " -> "" (empty string) After patch: " " -> " " (no change) I think we should remove your patch to restore the old behavior. The description (lib/string.c): * Note that the first trailing whitespace is replaced with a %NUL-terminator => The first trailing whitespace of a string that only has whitespace characters is the first whitespace The patch restores the old strim() semantics.

__bitmap_parse() and __bitmap_parselist() both take a pointer to a kernel buffer as a parameter and then cast it to a pointer to user buffer for use in cases when the parameter is_user indicates that the buffer is actually located in user space. This casting, and the casts in the callers, results in sparse noise like the following: warning: incorrect type in initializer (different address spaces) expected char const [noderef] <asn:1>*ubuf got char const *buf warning: cast removes address space of expression Since these casts are intentional, use __force to quiet the noise.

When SPIN_BUG_ON is triggered, the lock owner information is reported. But it is omitted when spinlock lockup is detected. This information is useful especially on the architectures which don't implement trigger_all_cpu_backtrace() that is called just after detecting lockup. So report it and also avoid message format duplication. Signed-off-by:

Currently termination logic (\0 or \n\0) is hardcoded in _kstrtoull(), avoid that for code reuse between kstrto*() and simple_strtoull(). Essentially, make them different only in termination logic. simple_strtoull() (and scanf(), BTW) ignores integer overflow, that's a bug we currently don't have guts to fix, making KSTRTOX_OVERFLOW hack necessary. Almost forgot: patch shrinks code size by about ~80 bytes on x86_64. Signed-off-by:

Depending on the implementation of the hardware blinking function in blink_set(), the led can support hardware blinking for some values of delay_on and delay_off and fall-back to software blinking for some other values. Turning off the blink_timer unconditionally before starting to blink make sure that a sequence like: OFF hardware blinking software blinking hardware blinking does not leave the software blinking timer active.

When calling the hardware blinking function implemented by blink_set(), the delay_on and delay_off values are not preserved across calls. Fix that and make the "timer" trigger work as expected when hardware blinking is available.
