2011-03-20niu: Rename NIU parent platform device name to fix conflict.David S. Miller1-1/+1
When the OF device driver bits were converted over to the platform device infrastructure in commit 74888760d40b3ac9054f9c5fa07b566c0676ba2d ("dt/net: Eliminate users of of_platform_{,un}register_driver") we inadvertantly created probing problems in the OF case. The NIU driver creates a dummy platform device to represent the board that contains one or more child NIU devices. Unfortunately we use the same name, "niu", as the OF device driver itself uses. The result is that we try to probe the dummy "niu" parent device we create, and since it has a NULL ofdevice pointer etc. everything explodes: [783019.128243] niu: niu.c:v1.1 (Apr 22, 2010) [783019.128810] Unable to handle kernel NULL pointer dereference [783019.128949] tsk->{mm,active_mm}->context = 000000000000039e [783019.129078] tsk->{mm,active_mm}->pgd = fffff803afc5a000 [783019.129206] \|/ ____ \|/ [783019.129213] "@'/ .. \`@" [783019.129220] /_| \__/ |_\ [783019.129226] \__U_/ [783019.129378] modprobe(2004): Oops [#1] [783019.129423] TSTATE: 0000000011001602 TPC: 0000000010052ff8 TNPC: 000000000061bbb4 Y: 00000000 Not tainted [783019.129542] TPC: <niu_of_probe+0x3c/0x2dc [niu]> [783019.129624] g0: 8080000000000000 g1: 0000000000000000 g2: 0000000010056000 g3: 0000000000000002 [783019.129733] g4: fffff803fc1da0c0 g5: fffff800441e2000 g6: fffff803fba84000 g7: 0000000000000000 [783019.129842] o0: fffff803fe7df010 o1: 0000000010055700 o2: 0000000000000000 o3: fffff803fbacaca0 [783019.129951] o4: 0000000000000080 o5: 0000000000777908 sp: fffff803fba866e1 ret_pc: 0000000010052ff4 [783019.130083] RPC: <niu_of_probe+0x38/0x2dc [niu]> [783019.130165] l0: fffff803fe7df010 l1: fffff803fbacafc0 l2: fffff803fbacaca0 l3: ffffffffffffffed [783019.130273] l4: 0000000000000000 l5: 000000007fffffff l6: fffff803fba86f40 l7: 0000000000000001 [783019.130382] i0: fffff803fe7df000 i1: fffff803fc20aba0 i2: 0000000000000000 i3: 0000000000000001 [783019.130490] i4: 0000000000000000 i5: 0000000000000000 i6: fffff803fba867a1 i7: 000000000062038c [783019.130614] I7: <platform_drv_probe+0xc/0x20> Fix by simply renaming the parent device to "niu-board".

2011-02-04niu: Fix races between up/down and get_stats.David S. Miller1-16/+45
As reported by Flavio Leitner, there is no synchronization to protect NIU's get_stats method from seeing a NULL pointer in either np->rx_rings or np->tx_rings. In fact, as far as ->ndo_get_stats is concerned, these values are set completely asynchronously. Flavio attempted to fix this using a RW semaphore, which in fact works most of the time. However, dev_get_stats() can be invoked from non-sleepable contexts in some cases, so this fix doesn't work in all cases. So instead, control the visibility of the np->{rx,tx}_ring pointers when the device is being brough up, and use properties of the device down sequence to our advantage. In niu_get_stats(), return immediately if netif_running() is false. The device shutdown sequence first marks the device as not running (by clearing the __LINK_STATE_START bit), then it performans a synchronize_rcu() (in dev_deactive_many()), and then finally it invokes the driver ->ndo_stop() method. This guarentees that all invocations of niu_get_stats() either see netif_running() as false, or they see the channel pointers before ->ndo_stop() clears them out. If netif_running() is true, protect against startup races by loading the np->{rx,tx}_rings pointer into a local variable, and punting if it is NULL. Use ACCESS_ONCE to prevent the compiler from reloading the pointer on us. Also, during open, control the order in which the pointers and the ring counts become visible globally using SMP write memory barriers. We make sure the np->num_{rx,tx}_rings value is stable and visible before np->{rx,tx}_rings is. Such visibility control is not necessary on the niu_free_channels() side because of the RCU sequencing that happens during device down as described above. We are always guarenteed that all niu_get_stats calls are finished, or will see netif_running() false, by the time ->ndo_stop is invoked.

2010-12-12drivers/net: don't use flush_scheduled_work()Tejun Heo1-1/+1
flush_scheduled_work() is on its way out. This patch contains simple conversions to replace flush_scheduled_work() usage with direct cancels and flushes. Directly cancel the used works on driver detach and flush them in other cases. The conversions are mostly straight forward and the only dangers are, * Forgetting to cancel/flush one or more used works. * Cancelling when a work should be flushed (ie. the work must be executed once scheduled whether the driver is detaching or not). I've gone over the changes multiple times but it would be much appreciated if you can review with the above points in mind. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: "David S.

2010-09-09niu: Fix kernel buffer overflow for ETHTOOL_GRXCLSRLALLBen Hutchings1-10/+6
niu_get_ethtool_tcam_all() assumes that its output buffer is the right size, and warns before returning if it is not. However, the output buffer size is under user control and ETHTOOL_GRXCLSRLALL is an unprivileged ethtool command. Therefore this is at least a local denial-of-service vulnerability. Change it to check before writing each entry and to return an error if the buffer is already full. Compile-tested only.

2010-06-28sparc/of: Move of_device fields into struct pdev_archdataGrant Likely1-3/+3
This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

These string query operations were supposed to be replaced by the generic get_sset_count() starting in 2007. Convert the remaining implementations. Also remove calls to these operations to initialise drvinfo->n_stats. The ethtool core code already does that.

2009-09-23BUILD_BUG_ON(): fix it and a couple of bogus uses of itJan Beulich1-1/+1
gcc permitting variable length arrays makes the current construct used for BUILD_BUG_ON() useless, as that doesn't produce any diagnostic if the controlling expression isn't really constant. Instead, this patch makes it so that a bit field gets used here. Consequently, those uses where the condition isn't really constant now also need fixing. Note that in the gfp.h, kmemcheck.h, and virtio_config.h cases MAYBE_BUILD_BUG_ON() really just serves documentation purposes - even if the expression is compile time constant (__builtin_constant_p() yields true), the array is still deemed of variable length by gcc, and hence the whole expression doesn't have the intended effect.

2009-06-18net: group address list and its countJiri Pirko1-2/+2
This patch is inspired by patch recently posted by Johannes Berg. Basically what my patch does is to group list and a count of addresses into newly introduced structure netdev_hw_addr_list. This brings us two benefits: 1) struct net_device becames a bit nicer. 2) in the future there will be a possibility to operate with lists independently on netdevices (with exporting right functions). I wanted to introduce this patch before I'll post a multicast lists conversion.

2009-05-30net: convert unicast addr listJiri Pirko1-3/+4
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.
