* SUNRPC: Fix a performance regression in the RPC authentication codeTrond Myklebust2008-11-201-2/+18
| | | | | | | | | | | | | | | | | Fix a regression reported by Max Kellermann whereby kernel profiling showed that his clients were spending 45% of their time in rpcauth_lookup_credcache. It turns out that although his processes had identical uid/gid/groups, generic_match() was failing to detect this, because the task->group_info pointers were not shared. This again lead to the creation of a huge number of identical credentials at the RPC layer. The regression is fixed by comparing the contents of task->group_info if the actual pointers are not identical.

| | * mac80211: remove ieee80211_notify_macJohannes Berg2008-11-181-22/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before ieee80211_notify_mac() was added, it was presented with the use case of using it to tell mac80211 that the association may have been lost because the firmware crashed/reset. Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested.

The addition of this system call matches analogous changes in 2.6.27 (dup3(), evenfd2(), signalfd4(), inotify_init1(), epoll_create1(), pipe2()) which added new system calls that differed from analogous traditional system calls in adding a flags argument that can be used to access additional functionality. The accept4() system call is exactly the same as accept(), except that it adds a flags bit-mask argument. Two flags are initially implemented. (Most of the new system calls in 2.6.27 also had both of these flags.) SOCK_CLOEXEC causes the close-on-exec (FD_CLOEXEC) flag to be enabled for the new file descriptor returned by accept4(). This is a useful security feature to avoid leaking information in a multithreaded program where one thread is doing an accept() at the same time as another thread is doing a fork() plus exec(). More details here: http://udrepper.livejournal.com/20407.html "Secure File Descriptor Handling", Ulrich Drepper). The other flag is SOCK_NONBLOCK, which causes the O_NONBLOCK flag to be enabled on the new open file description created by accept4(). (This flag is merely a convenience, saving the use of additional calls fcntl(F_GETFL) and fcntl (F_SETFL) to achieve the same result. Here's a test program. Works on x86-32. Should work on x86-64, but I (mtk) don't have a system to hand to test with. It tests accept4() with each of the four possible combinations of SOCK_CLOEXEC and SOCK_NONBLOCK set/clear in 'flags', and verifies that the appropriate flags are set on the file descriptor/open file description returned by accept4(). I tested Ulrich's patch in this thread by applying against 2.6.28-rc2, and it passes according to my test program. /* test_accept4.c Copyright (C) 2008, Linux Foundation, written by Michael Kerrisk <mtk.manpages@gmail.com> Licensed under the GNU GPLv2 or later. */ #define _GNU_SOURCE #include <unistd.h> #include <sys/syscall.h> #include <sys/socket.h> #include <netinet/in.h> #include <stdlib.h> #include <fcntl.h> #include <stdio.h> #include <string.h> #define PORT_NUM 33333 #define die(msg) do { perror(msg); exit(EXIT_FAILURE); } while (0) /**********************************************************************/ /* The following is what we need until glibc gets a wrapper for accept4() */ /* Flags for socket(), socketpair(), accept4() */ #ifndef SOCK_CLOEXEC #define SOCK_CLOEXEC O_CLOEXEC #endif #ifndef SOCK_NONBLOCK #define SOCK_NONBLOCK O_NONBLOCK #endif #ifdef __x86_64__ #define SYS_accept4 288 #elif __i386__ #define USE_SOCKETCALL 1 #define SYS_ACCEPT4 18 #else #error "Sorry -- don't know the syscall # on this architecture" #endif static int accept4(int fd, struct sockaddr *sockaddr, socklen_t *addrlen, int flags) { printf("Calling accept4(): flags = %x", flags); if (flags != 0) { printf(" ("); if (flags & SOCK_CLOEXEC) printf("SOCK_CLOEXEC"); if ((flags & SOCK_CLOEXEC) && (flags & SOCK_NONBLOCK)) printf(" "); if (flags & SOCK_NONBLOCK) printf("SOCK_NONBLOCK"); printf(")"); } printf("\n"); #if USE_SOCKETCALL long args[6]; args[0] = fd; args[1] = (long) sockaddr; args[2] = (long) addrlen; args[3] = flags; return syscall(SYS_socketcall, SYS_ACCEPT4, args); #else return syscall(SYS_accept4, fd, sockaddr, addrlen, flags); #endif } /**********************************************************************/ static int do_test(int lfd, struct sockaddr_in *conn_addr, int closeonexec_flag, int nonblock_flag) { int connfd, acceptfd; int fdf, flf, fdf_pass, flf_pass; struct sockaddr_in claddr; socklen_t addrlen; printf("=======================================\n"); connfd = socket(AF_INET, SOCK_STREAM, 0); if (connfd == -1) die("socket"); if (connect(connfd, (struct sockaddr *) conn_addr, sizeof(struct sockaddr_in)) == -1) die("connect"); addrlen = sizeof(struct sockaddr_in); acceptfd = accept4(lfd, (struct sockaddr *) &claddr, &addrlen, closeonexec_flag | nonblock_flag); if (acceptfd == -1) { perror("accept4()"); close(connfd); return 0; } fdf = fcntl(acceptfd, F_GETFD); if (fdf == -1) die("fcntl:F_GETFD"); fdf_pass = ((fdf & FD_CLOEXEC) != 0) == ((closeonexec_flag & SOCK_CLOEXEC) != 0); printf("Close-on-exec flag is %sset (%s); ", (fdf & FD_CLOEXEC) ?

| | | | | | | | | | | | | | | | | | | This is the next page of the scm recursion story (the commit f8d570a4 net: Fix recursive descent in __scm_destroy()). In function scm_fp_dup(), the INIT_LIST_HEAD(&fpl->list) of newly created fpl is done *before* the subsequent memcpy from the old structure and thus the freshly initialized list is overwritten. But that's OK, since this initialization is not required at all, since the fpl->list is list_add-ed at the destruction time in any case (and is unused in other code), so I propose to drop both initializations, rather than moving it after the memcpy.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before commit b6c40d68ff6498b7f63ddf97cf0aa818d748dee7 ("net: only invoke dev->change_rx_flags when device is UP"), the dsa driver could sort-of get away with only fiddling with the master interface's allmulti/promisc counts in ->change_rx_flags() and not touching them in ->open() or ->stop(). After this commit (note that it was merged almost simultaneously with the dsa patches, which is why this wasn't caught initially), the breakage that was already there became more apparent.

* | net: unix: fix inflight counting bug in garbage collectorMiklos Szeredi2008-11-092-19/+61
|/ | | | | | | | | | | | | | | | | | | | | | | Previously I assumed that the receive queues of candidates don't change during the GC. This is only half true, nothing can be received from the queues (see comment in unix_gc()), but buffers could be added through the other half of the socket pair, which may still have file descriptors referring to it. This can result in inc_inflight_move_tail() erronously increasing the "inflight" counter for a unix socket for which dec_inflight() wasn't previously called. This in turn can trigger the "BUG_ON(total_refs < inflight_refs)" in a later garbage collection run. Fix this by only manipulating the "inflight" counter for sockets which are candidates themselves. Duplicating the file references in unix_attach_fds() is also needed to prevent a socket becoming a candidate for GC while the skb that contains it is not yet queued.

So when the second WLAN device (the hso device, with the EEE PC WLAN being the first) comes along rfkill_check_duplicity returns a negative value and so rfkill_register returns an error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | __scm_destroy() walks the list of file descriptors in the scm_fp_list pointed to by the scm_cookie argument. Those, in turn, can close sockets and invoke __scm_destroy() again. There is nothing which limits how deeply this can occur. The idea for how to fix this is from Linus. Basically, we do all of the fput()s at the top level by collecting all of the scm_fp_list objects hit by an fput(). Inside of the initial __scm_destroy() we keep running the list until it is empty.

| * | ipv6: fix run pending DAD when interface becomes readyBenjamin Thery2008-11-051-1/+3

In some case, pending IPv6 DADs are not executed when the device becomes ready. I observed this while doing some tests with kvm. If I assign an IPv6 address to my interface eth0 (kvm driver rtl8139) when it is still down then the address is flagged tentative (IFA_F_TENTATIVE). Then, I set eth0 up, and to my surprise, the address stays 'tentative', no DAD is executed and the address can't be pinged. I also observed the same behaviour, without kvm, with virtual interfaces types macvlan and veth. Some easy steps to reproduce the issue with macvlan: 1. ip link add link eth0 type macvlan 2. ip -6 addr add 2003::ab32/64 dev macvlan0 3. ip addr show dev macvlan0 ... inet6 2003::ab32/64 scope global tentative ... 4. ip link set macvlan0 up 5. ip addr show dev macvlan0 ... inet6 2003::ab32/64 scope global tentative ... Address is still tentative I think there's a bug in net/ipv6/addrconf.c, addrconf_notify(): addrconf_dad_run() is not always run when the interface is flagged IF_READY. Currently it is only run when receiving NETDEV_CHANGE event. Looks like some (virtual) devices doesn't send this event when becoming up. For both NETDEV_UP and NETDEV_CHANGE events, when the interface becomes ready, run_pending should be set to 1. Patch below. 'run_pending = 1' could be moved below the if/else block but it makes the code less readable. Signed-off-by: Benjamin Thery <benjamin.thery@bull.net> Signed-off-by: David S.
