2011-12-05e1000e: hitting BUG_ON() from napi_enableBruce Allan
Based on a patch from Mike McElroy created against the out-of-tree e1000e driver: Hitting the BUG_ON in napi_enable(). Code inspection shows that this can only be triggered by calling napi_enable() twice without an intervening napi_disable(). I saw the following sequence of events in the stack trace: 1) We simulated a cable pull using an Extreme switch. 2) e1000_tx_timeout() was entered. 3) e1000_reset_task() was called. Saw the message from e_err() in the console log. 4) e1000_reinit_locked was called. This function calls e1000_down() and e1000_up(). These functions call napi_disable() and napi_enable() respectively. 5) Then on another thread, a monitor task saw carrier was down and executed 'ip set link down' and 'ip set link up' commands. 6) Saw the '_E1000_RESETTING'warning fron the e1000_close function. 7) Either the e1000_open() executed between the e1000_down() and e1000_up() calls in step 4 or the e1000_open() call executed after the e1000_up() call. In either case, napi_enable() is called twice which triggers the BUG_ON.

RED is useful for high throughput routers, I doubt many linux machines act as such devices. I was considering adding Adaptative RED (Sally Floyd, Ramakrishna Gummadi, Scott Shender), August 2001 In this version, maxp is dynamic (from 1% to 50%), and user only have to setup min_th (target average queue size) (max_th and wq (burst in linux RED) are automatically setup) By the way it seems we have a small bug in red_change() if (skb_queue_empty(&sch->q)) red_end_of_idle_period(&q->parms); First, if queue is empty, we should call red_start_of_idle_period(&q->parms); Second, since we dont use anymore sch->q, but q->qdisc, the test is meaningless. Oh well... [PATCH] sch_red: fix red_change() Now RED is classful, we must check q->qdisc->q.qlen, and if queue is empty, we start an idle period, not end it.

2011-12-01ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita
The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

2011-12-01bridge: master device stuck in no-carrier state forever when in user-stp modeVitalii Demianets
When in user-stp mode, bridge master do not follow state of its slaves, so after the following sequence of events it can stuck forever in no-carrier state: 1) turn stp off 2) put all slaves down - master device will follow their state and also go in no-carrier state 3) turn stp on with bridge-stp script returning 0 (go to the user-stp mode) Now bridge master won't follow slaves' state and will never reach running state. This patch solves the problem by making user-stp and kernel-stp behavior similar regarding master following slaves' states.

Indirect access via address and data port is supported as well: insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Furthermore, the following mode parameter can be defined: clk: External oscillator clock frequency (default=16000000 [16 MHz]) cir: CPU interface register (default=0x40 [DSC]) bcr: Bus configuration register (default=0x40 [CBY]) cor: Clockout register (default=0x00) Note: for clk, cir, bcr and cor, the first argument re-defines the default for all other devices, e.g.: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000 Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: David S.

Commit 4a54c8c16 introduced raid-repair, killing the individual readpage_io_failed_hook entries from inode.c and disk-io.c. Commit 4bb31e92 introduced new readahead code, adding a readpage_io_failed_hook to disk-io.c. The raid-repair commit had logic to disable raid-repair, if readpage_io_failed_hook is set. Thus, the readahead commit effectively disabled raid-repair for meta data. This commit changes the logic to always attempt raid-repair when needed and call the readpage_io_failed_hook in case raid-repair fails. This is much more straight forward and should have been like that from the beginning.

2011-11-30netem: rate extensionHagen Paul Pfeifer
Currently netem is not in the ability to emulate channel bandwidth. Only static delay (and optional random jitter) can be configured. To emulate the channel rate the token bucket filter (sch_tbf) can be used. But TBF has some major emulation flaws. The buffer (token bucket depth/rate) cannot be 0. Also the idea behind TBF is that the credit (token in buckets) fills if no packet is transmitted. So that there is always a "positive" credit for new packets. In real life this behavior contradicts the law of nature where nothing can travel faster as speed of light. E.g.: on an emulated 1000 byte/s link a small IPv4/TCP SYN packet with ~50 byte require ~0.05 seconds - not 0 seconds. Netem is an excellent place to implement a rate limiting feature: static delay is already implemented, tfifo already has time information and the user can skip TBF configuration completely. This patch implement rate feature which can be configured via tc. e.g: tc qdisc add dev eth0 root netem rate 10kbit To emulate a link of 5000byte/s and add an additional static delay of 10ms: tc qdisc add dev eth0 root netem delay 10ms rate 5KBps Note: similar to TBF the rate extension is bounded to the kernel timing system. Depending on the architecture timer granularity, higher rates (e.g. 10mbit/s and higher) tend to transmission bursts. Also note: further queues living in network adaptors; see ethtool(8).

2011-11-30ARM: 7181/1: Restrict kprobes probing SWP instructions to ARMv5 and belowJon Medhurst (Tixy)
The SWP instruction is deprecated on ARMv6 and with ARMv7 it will be UNDEFINED when CONFIG_SWP_EMULATE is selected. In this case, probing a SWP instruction will cause an oops when the kprobes emulation code executes an undefined instruction. As the SWP instruction should be rare or non-existent in kernels for ARMv6 and later, we can simply avoid these problems by not allowing probing of these.
