This patch fixes a regression introduced by commit "MIPS: Alchemy: MTX-1: Use linux gpio api." (bb706b28) which broke PCI bus operation. The problem is caused by alchemy_gpio2_enable() which resets the GPIO2 block. Two PCI signals (PCI_SERR and PCI_RST) are connected to GPIO2 and they obviously do not to like the reset. Since GPIO2 is correctly initialized by the boot monitor (YAMON) it is not necessary to call this function, so just remove it. Also replace gpio_set_value() with alchemy_gpio_set_value() to avoid problems in case gpiolib gets initialized after PCI. And since alchemy gpio_set_value() calls au_sync() we don't have to au_sync() again later.

Quoting from Jiri Slaby's patch of a similar nature for x86: When initrd is in use and a driver does request_module() in its module_init (i.e. __initcall or device_initcall), a modprobe process is created with VDSO mapping. But VDSO is inited even in __initcall, i.e. on the same level (at the same time), so it may not be inited yet (link order matters). Move init_vdso up to subsys_initcall to avoid the issue.

The .data..init_task output section was missing a load offset causing a popwerpc target to fail to boot. Sean MacLennan tracked it down to the definition of INIT_TASK_DATA_SECTION(). There are only two users of INIT_TASK_DATA_SECTION() in the kernel today: cris and popwerpc. cris do not support relocatable kernels and is thus not impacted by this change. Fix INIT_TASK_DATA_SECTION() to specify load offset like all other output sections.

There's a couple of nasty bugs lurking in our huge page hashing code. First, we don't check the access permission atomically with setting the _PAGE_BUSY bit, which means that the PTE value we end up using for the hashing might be different than the one we have checked the access permissions for. We've seen cases where that leads us to try to use an invalidated PTE for hashing, causing all sort of "interesting" issues. Then, we also failed to set _PAGE_DIRTY on a write access. Finally, a minor tweak but we should return 0 when we find the PTE busy, in order to just re-execute the access, rather than 1 which means going to do_page_fault().

由 Benjamin Herrenschmidt 提交于
Instead of adding _PAGE_PRESENT to the access permission mask in each low level routine independently, we add it once from hash_page(). We also move the preliminary access check (the racy one before the PTE is locked) up so it applies to the huge page case. This duplicates code in __hash_page_huge() which we'll remove in a subsequent patch to fix a race in there. Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

If the hypervisor gives us an error on a hugepage insert we panic.

When parsing the objdump disassembly output we can have goto labels that are valid hex numbers and thus get confused with lines with machine code. Handle the common case of a label that has nothing after it and other cases where there is just source code by validating the resulting "ip". It is still possible that we find goto labels that are in the function address range, but only if they are located before the real address we should be OK. A change in the objdump output to have a clear marker separating addresses from the disassembly would come handy, but we would still have to deal with older versions.

Fix the security problem in the CIFS filesystem DNS lookup code in which a malicious redirect could be installed by a random user by simply adding a result record into one of their keyrings with add_key() and then invoking a CIFS CFS lookup [CVE-2010-2524]. This is done by creating an internal keyring specifically for the caching of DNS lookups. To enforce the use of this keyring, the module init routine creates a set of override credentials with the keyring installed as the thread keyring and instructs request_key() to only install lookup result keys in that keyring. The override is then applied around the call to request_key(). This has some additional benefits when a kernel service uses this module to request a key: (1) The result keys are owned by root, not the user that caused the lookup. (2) The result keys don't pop up in the user's keyrings. (3) The result keys don't come out of the quota of the user that caused the lookup. The keyring can be viewed as root by doing cat /proc/keys: 2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4 It can then be listed with 'keyctl list' by root. # keyctl list 0x2a0ca6c3 1 key in keyring: 726766307: --alswrv 0 0 dns_resolver: foo.bar.com Signed-off-by: NDavid Howells <dhowells@redhat.com> Reviewed-and-Tested-by: NJeff Layton <jlayton@redhat.com> Acked-by: NSteve French <smfrench@gmail.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls, we can pass a bad return value and/or error indication for the system call to audit_syscall_exit(). This happens when TIF_NEED_RESCHED was set as the system call returned, so we went out to schedule() and came back to the exit-audit fast-path. The fix is to reload the user return value register from the pt_regs before using it for audit_syscall_exit(). Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit system call fast paths work slightly differently, so that they always leave the fast path entirely to reschedule and don't return there, so they don't have the analogous bugs.

Immediately following an exit from the kdb shell the kgdb_connected variable should be set to zero, unless there are breakpoints planted. If the kgdb_connected variable is not zeroed out with kdb, it is impossible to turn off kdb. This patch is merely a work around for now, the real fix will check for the breakpoints.

In the process of merging kdb to the mainline, the kdb lsmod command stopped printing the base load address of kernel modules. This is needed for using kdb in conjunction with external tools such as gdb. Simply restore the functionality by adding a kdb_printf for the base load address of the kernel modules.

The gdbserial protocol handler should return an empty packet instead of an error string when ever it responds to a command it does not implement. The problem cases come from a debugger client sending qTBuffer, qTStatus, qSearch, qSupported. The incorrect response from the gdbstub leads the debugger clients to not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior. Signed-off-by: NJason Wessel <jason.wessel@windriver.com> Signed-off-by: NDongdong Deng <dongdong.deng@windriver.com>
