* net: fix sk_forward_alloc corruptionsEric Dumazet2010-05-29
| | | | | | | | | | | | | | | | | As David found out, sock_queue_err_skb() should be called with socket lock hold, or we risk sk_forward_alloc corruption, since we use non atomic operations to update this field. This patch adds bh_lock_sock()/bh_unlock_sock() pair to three spots. (BH already disabled) 1) skb_tstamp_tx() 2) Before calling ip_icmp_error(), in __udp4_lib_err() 3) Before calling ipv6_icmp_error(), in __udp6_lib_err() Reported-by: Anton Blanchard <anton@samba.org> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

* fs_enet: Adjust BDs after tx errorMark Ware2010-05-29
| | | | | | | | | | | | | | | | | This patch fixes an occasional transmit lockup in the mac-fcc which occurs after a tx error. The test scenario had the local port set to autoneg and the other end fixed at 100FD, resulting in a large number of late collisions. According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after a tx error occurs, TBPTR may sometimes point beyond BDs still marked as ready. This patch walks back through the BDs and points TBPTR to the earliest one marked as ready. Tested on a custom board with a MPC8280.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we disallow GSO packets on the IPv6 forward path. This patch fixes this. Note that I discovered that our existing GSO MTU checks (e.g., IPv4 forwarding) are buggy in that they skip the check altogether, when they really should be checking gso_size + header instead. I have also been lazy here in that I haven't bothered to segment the GSO packet by hand before generating an ICMP message. Someone should add that to be 100% correct.

But it is unsafe to protect two threads, one using regular lock_sock/release_sock, one using lock_sock_bh/unlock_sock_bh This patch changes lock_sock_bh to be careful against 'owned' state. If owned is found to be set, we must take the slow path. lock_sock_bh() now returns a boolean to say if the slow path was taken, and this boolean is used at unlock_sock_bh time to call the appropriate unlock function. After this change, BH are either disabled or enabled during the lock_sock_bh/unlock_sock_bh protected section. This might be misleading, so we rename these functions to lock_sock_fast()/unlock_sock_fast().

* | proc_dointvec: write a single valueJ. R. Okajima2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit 00b7c3395aec3df43de5bd02a3c5a099ca51169f "sysctl: refactor integer handling proc code" modified the behaviour of writing to /proc. Before the commit, write("1\n") to /proc/sys/kernel/printk succeeded. But now it returns EINVAL. This commit supports writing a single value to a multi-valued entry. Signed-off-by: J. R.

| * | wimax/i2400m: fix bad race condition check in RX pathInaky Perez-Gonzalez2010-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2400m->rx_roq data structure is protected against race conditions with a reference count (i2400m->rx_roq_refcount); the pointer can be read-referenced under the i2400m->rx_lock spinlock. The code in i2400m_rx_edata() wasn't properly following access protocol, performing an invalid check on i2400m->rx_roq (which is cleared to NULL when the refcount drops to zero). As such, it was missing to detect when the data structure is no longer valid and oopsing with a NULL pointer dereference. This commit fixes said check by verifying, under the rx_lock spinlock, that i2400m->rx_roq is non-NULL and then increasing the reference count before dropping the spinlock.

| * | ath9k: remove VEOL support for ad-hocFelix Fietkau2010-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With VEOL, Beacon transmission in ad-hoc does not currently work. I believe for larger ad-hoc networks, VEOL is too unreliable, as it can get beacon transmissions stuck during synchronization. Use SWBA based beacon trasmission similar to AP mode instead.
