2009-11-24Fixed a regression in resync decission code drbd_uuid_compare() [Bugz 260]Philipp Reisner
Since 8.3.3 we fail to do the resync when a partial resynch is not possible, but a full synch is necessary. This regression was introduced with 7101539930c0a89146959e7a39c09ad9c3516434 Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
2009-11-24add missing state change on corrupt packet header in drbd_recv_headerLars Ellenberg
Otherwise the 'state fixup' in the receiver will change to Unconnected, but the receiver will terminate itself, and any attempt at 'down'ing that drbd later will block forever. see also Bugz. #259 Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>
2009-11-24fix in-kernel configuration serializationLars Ellenberg
this is uncritical, as we still also serialize in userland, but to correctly serialize on the CONFIG_PENDING bit, it must be wait_event(state_wait, \!test_and_set_bit) Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com> Signed-off-by: Lars Ellenberg <lars.ellenberg@linbit.com>

2009-11-24perf symbols: Simplify symbol machinery setupArnaldo Carvalho de Melo
And also express its configuration toggles via a struct. Now all one has to do is to call symbol__init(NULL) if the defaults are OK, or pass a struct symbol_conf pointer with the desired configuration. If a tool uses kernel_maps__find_symbol() to look at the kernel and modules mappings for a symbol but didn't call symbol__init() first, that will generate a one time warning too, alerting the subcommand developer that symbol__init() must be called.

2009-11-24perf tools: Fix compilation on powerpcPaul Mackerras
Currently, perf fails to compile on powerpc with this error: CC util/header.o In file included from util/../perf.h:17, from util/header.c:9: util/../../../arch/powerpc/include/asm/unistd.h:360:27: error: linux/linkage.h: No such file or directory make: *** [util/header.o] Error 1 The reason is that we still have a #define __KERNEL__ in effect at the point where <asm/unistd.h> gets included, which means we get extra stuff that we don't need or want. This fixes the problem by undefining __KERNEL__ once we have included the file for which we need __KERNEL__ defined.

2009-11-24remove CONFIG_SECURITY_FILE_CAPABILITIES compile optionSerge E. Hallyn
As far as I know, all distros currently ship kernels with default CONFIG_SECURITY_FILE_CAPABILITIES=y. Since having the option on leaves a 'no_file_caps' option to boot without file capabilities, the main reason to keep the option is that turning it off saves you (on my s390x partition) 5k. In particular, vmlinux sizes came to: without patch fscaps=n: 53598392 without patch fscaps=y: 53603406 with this patch applied: 53603342 with the security-next tree. Against this we must weigh the fact that there is no simple way for userspace to figure out whether file capabilities are supported, while things like per-process securebits, capability bounding sets, and adding bits to pI if CAP_SETPCAP is in pE are not supported with SECURITY_FILE_CAPABILITIES=n, leaving a bit of a problem for applications wanting to know whether they can use them and/or why something failed. It also adds another subtly different set of semantics which we must maintain at the risk of severe security regressions. So this patch removes the SECURITY_FILE_CAPABILITIES compile option. It drops the kernel size by about 50k over the stock SECURITY_FILE_CAPABILITIES=y kernel, by removing the cap_limit_ptraced_target() function.

2009-11-24SELinux: print denials for buggy kernel with unknown permsEric Paris
Historically we've seen cases where permissions are requested for classes where they do not exist. In particular we have seen CIFS forget to set i_mode to indicate it is a directory so when we later check something like remove_name we have problems since it wasn't defined in tclass file. This used to result in a avc which included the permission 0x2000 or something. Currently the kernel will deny the operations (good thing) but will not print ANY information (bad thing). First the auditdeny field is no extended to include unknown permissions. After that is fixed the logic in avc_dump_query to output this information isn't right since it will remove the permission from the av and print the phrase "<NULL>". This takes us back to the behavior before the classmap rewrite. Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
2009-11-24drm/fb: fix FBIOGET/PUT_VSCREENINFO pixel clock handlingClemens Ladisch
When the framebuffer driver does not publish detailed timing information for the current video mode, the correct value for the pixclock field is zero, not -1. Since pixclock is actually unsigned, the value -1 would be interpreted as 4294967295 picoseconds (i.e., about 4 milliseconds) by register_framebuffer() and userspace programs. This patch allows X.org's fbdev driver to work.

2009-11-24drm: make sure page protections are updated after changing vm_flagsJeremy Fitzhardinge
Some architectures compute ->vm_page_prot depending on ->vm_flags, so we need to update the protections after adjusting the flags. AFAIK this only affects running X under Xen; without this patch you get lots of coloured blobs on the screen, or maybe a complete lockup. Or anything really. But that still depends on lots of out-of-tree stuff, so I don't think there are any consequences for anyone else. But it is wrong in principle.

2009-11-24drm/radeon/kms: Report vga connector is connected according to ddc_probeJerome Glisse
On broken EDID we were reporting vga connector to be disconnected even if ddc probe did found a monitor. This patch report that the connector is connected on such case. This allow drm to add a fail safe mode (800x600 at the time of this patch) thus user can boot and later add a mode which match its monitor capabilities.

2009-11-24drm: mm always protect change to unused_nodes with unused_lock spinlockJerome Glisse
unused_nodes modification needs to be protected by unused_lock spinlock. Here is an example of an usage where there is no such protection without this patch. Process 1: 1-drm_mm_pre_get(this function modify unused_nodes list) 2-spin_lock(spinlock protecting mm struct) 3-drm_mm_put_block(this function might modify unused_nodes list but doesn't protect modification with unused_lock) 4-spin_unlock(spinlock protecting mm struct) Process2: 1-drm_mm_pre_get(this function modify unused_nodes list) At this point Process1 & Process2 might both be doing modification to unused_nodes list. This patch add unused_lock protection into drm_mm_put_block to avoid such issue. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-11-24drm/radeon/kms: Disable TV load detect on RS400,RC410,RS480Jerome Glisse
RS400,RC410,RS480 chipset seems to report a lot of false positive with load detect on TV output. We haven't yet found a way to make load detect reliable on those chipset, thus just disable it for TV output. Would avoid user to experience phantom screen because X believe there is a monitor connected to the TV output.

2009-11-24drm/radeon/kms: read back register before writing in IIO.Dave Airlie
This fixes RH bugzilla #527874. On resume the atom posting wasn't working, however vbe posting was going fine, after 2 weeks over irc, and 8 hrs with the hardware, I tracked it down to the memory device table and it access the MC registers via IIO, it appears the rv515 atom iio table might not be fully functional, so adding a readback before doing a write either provides enough delay to make things resume correctly. Thanks to Peng Huang at Red Hat for coming to Brisbane. Signed-off-by: Dave Airlie <airlied@redhat.com>
