2012-12-05net: neighbour: prohibit negative value for unres_qlen_bytes parameterShan Wei
unres_qlen_bytes and unres_qlen are int type. But multiple relation(unres_qlen_bytes = unres_qlen * SKB_TRUESIZE(ETH_FRAME_LEN)) will cause type overflow when seting unres_qlen. e.g. $ echo 1027506 > /proc/sys/net/ipv4/neigh/eth1/unres_qlen $ cat /proc/sys/net/ipv4/neigh/eth1/unres_qlen 1182657265 $ cat /proc/sys/net/ipv4/neigh/eth1/unres_qlen_bytes -2147479756 The gutted value is not that we setting。 But user/administrator don't know this is caused by int type overflow. what's more, it is meaningless and even dangerous that unres_qlen_bytes is set with negative number. Because, for unresolved neighbour address, kernel will cache packets without limit in __neigh_event_send()(e.g. (u32)-1 = 2GB). Signed-off-by: Shan Wei <davidshan@tencent.com> Signed-off-by: David S.

2012-12-05SMB3 mounts fail with access denied to some serversSteve French
We were checking incorrectly if signatures were required to be sent, so were always sending signatures after the initial session establishment. For SMB3 mounts (vers=3.0) this was a problem because we were putting SMB2 signatures in SMB3 requests which would cause access denied on mount (the tree connection would fail). This might also be worth considering for stable (for 3.7), as the error message on mount (access denied) is confusing to users and there is no workaround if the server is configured to only support smb3.0. I am ok either way. CC: stable <stable@kernel.org> Signed-off-by: Steve French <smfrench@gmail.com> Reviewed-by: Jeff Layton <jlayton@redhat.com>

2012-12-05cifs: ensure we revalidate the inode after readdir if cifsacl is enabledJeff Layton
Otherwise, "ls -l" will simply show the ownership of the files as the default mnt_uid/gid. This may make "ls -l" performance on large directories super-suck in some cases, but that's the cost of cifsacl. One possibility to make it suck less would be to somehow proactively dispatch the ACL requests asynchronously from readdir codepath, but that's non-trivial to implement.

Error out with a clear error message if there is no unc= option. The existing code doesn't handle this in a clear fashion, and the check for a UNCip option with no UNC string is just plain wrong. Later, we'll fix the code to not require a unc= option, but for now we need this to at least clarify why people are getting errors about DFS parsing. With this change we can also get rid of some later NULL pointer checks since we know the UNC and UNCip will never be NULL there.

2012-12-05default authentication needs to be at least ntlmv2 security for cifs mountsSteve French
We had planned to upgrade to ntlmv2 security a few releases ago, and have been warning users in dmesg on mount about the impending upgrade, but had to make a change (to use nltmssp with ntlmv2) due to testing issues with some non-Windows, non-Samba servers. The approach in this patch is simpler than earlier patches, and changes the default authentication mechanism to ntlmv2 password hashes (encapsulated in ntlmssp) from ntlm (ntlm is too weak for current use and ntlmv2 has been broadly supported for many, many years).

2012-12-05MIPS: Fix endless loop when processing signals for kernel tasksDmitry Adamushko
The problem occurs [1] when a kernel-mode task returns from a system call with a pending signal. A real-life scenario is a child of 'khelper' returning from a failed kernel_execve() in ____call_usermodehelper() [ kernel/kmod.c ]. kernel_execve() fails due to a pending SIGKILL, which is the result of "kill -9 -1" (at least, busybox's init does it upon reboot). The loop is as follows: * syscall_exit_work: - work_pending: // start_of_the_loop - work_notifysig: - do_notify_resume() - do_signal() - if (!user_mode(regs)) return; - resume_userspace // TIF_SIGPENDING is still set - work_pending // so we call work_pending => goto // start_of_the_loop More information can be found in another LKML thread: http://www.serverphorums.com/read.php?12,457826 [1] The problem was also reproduced on !CONFIG_VM86 x86, and the following fix was accepted. http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=29a2e2836ff9ea65a603c89df217f4198973a74f Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/3571/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2012-12-05hwmon: (coretemp) Drop dependency on PCI for TjMax detection on Atom CPUsGuenter Roeck
So far, we use the NM10 Express Chipset PCI chip ID to detect TjMax for Atom CPUs with model 0x1c. As it turns out, we can use the CPU stepping (x86_mask) for the same purpose; stepping is 10 for all model 0x1c CPUs with TjMax of 100 degrees C. This was verified by checking the output of /proc/cpuinfo for the respective CPUs (D4xx, D5xx, N4xx, N5xx). Other CPUs currently covered by the same code (Exx, Z6xx, Z2460) are not supported by the NM10 Express Chipset. Most of those CPUs have TjMax of 90 degrees C, except for E6xxT models which have a TjMax of 110 degrees C. E6xxT CPUs can however not be detected by software. Calculate TjMax for Atom CPUs as follows. Note that the listed values are not correct in some cases (230, 330). tjmax_table is used for those to override the default values. ID Stepping TjMax Models 0x1c 10 100 D4xx, N4xx, D5xx, N5xx 0x1c not 10 90 Z5xx, N2xx, 230, 330, others 0x26 - 90 Atom Tunnel Creek (Exx), Lincroft (Z6xx) 0x27 - 90 Atom Medfield (Z2460) 0x36 - 100 Atom Cedar Trail (N2xxx, D2xxx) Also drop the module dependency on PCI.
