There is a memory leak happening in lpm_trie map_free callback function trie_free. The trie structure itself does not get freed. Also, trie_free function did not do synchronize_rcu before freeing various data structures. This is incorrect as some rcu_read_lock region(s) for lookup, update, delete or get_next_key may not complete yet. The fix is to add synchronize_rcu in the beginning of trie_free. The useless spin_lock is removed from this function as well.

Commit ebeeb1ad ("rds: tcp: use rds_destroy_pending() to synchronize netns/module teardown and rds connection/workq management") adds an rcu read critical section to __rd_conn_create.

The offending commit wrongly assumes 1:1 mapping between block and q. However, there are multiple blocks for a single q for classful qdiscs. Since the obscure tc_u_common sharing mechanism expects it to be shared among a qdisc, fix it by storing q pointer in case the block is not shared.

Since mlxsw_sp_fib_create() and mlxsw_sp_mr_table_create() use ERR_PTR macro to propagate int err through return of a pointer, the return value is not NULL in case of failure. So if one of the calls fails, one of vr->fib4, vr->fib6 or vr->mr4_table is not NULL and mlxsw_sp_vr_is_used wrongly assumes that vr is in use which leads to crash like following one: [ 1293.949291] BUG: unable to handle kernel NULL pointer dereference at 00000000000006c9 [ 1293.952729] IP: mlxsw_sp_mr_table_flush+0x15/0x70 [mlxsw_spectrum] Fix this by using local variables to hold the pointers and set vr->* only in case everything went fine.

This fixes a compile problem of some user space applications by not including linux/libc-compat.h in uapi/if_ether.h. linux/libc-compat.h checks which "features" the header files, included from the libc, provide to make the Linux kernel uapi header files only provide no conflicting structures and enums. If a user application mixes kernel headers and libc headers it could happen that linux/libc-compat.h gets included too early where not all other libc headers are included yet. Then the linux/libc-compat.h would not prevent all the redefinitions and we run into compile problems. This patch removes the include of linux/libc-compat.h from uapi/if_ether.h to fix the recently introduced case, but not all as this is more or less impossible. It is no problem to do the check directly in the if_ether.h file and not in libc-compat.h as this does not need any fancy glibc header detection as glibc never provided struct ethhdr and should define __UAPI_DEF_ETHHDR by them self when they will provide this. The following test program did not compile correctly any more: #include <linux/if_ether.h> #include <netinet/in.h> #include <linux/in.h> int main(void) { return 0; } Fixes: 6926e041 ("uapi/if_ether.h: prevent redefinition of struct ethhdr") Reported-by: NGuillaume Nault <g.nault@alphalink.fr> Cc: <stable@vger.kernel.org> # 4.15 Signed-off-by: NHauke Mehrtens <hauke@hauke-m.de> Signed-off-by: NDavid S.

The control channel calls registered callbacks when control messages such as XDomain protocol messages are received. The control channel handling is done in a worker running on system workqueue which means the networking driver can't run tear down flow which includes sending disconnect request and waiting for a reply in the same worker. Otherwise reply is never received (as the work is already running) and the operation times out. To fix this run disconnect ThunderboltIP flow asynchronously once ThunderboltIP logout message is received.

IPv6 doesn't work on the MacchiatoBIN board. It is caused by broken multicast address filter in the mvpp2 driver. The driver loads doesn't load any multicast entries if "allmulti" is not set. This condition should be reversed. The condition !netdev_mc_empty(dev) is useless (because netdev_for_each_mc_addr is nop if the list is empty). This patch also fixes a possible overflow of the multicast list - if mvpp2_prs_mac_da_accept fails, we set the allmulti flag and retry.

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al.
