2013-08-04ACPI / video: improve quirk check in acpi_video_bqc_quirk()Felipe Contreras1-1/+1
If the _BCL package ordering is descending, the first level (br->levels[2]) is likely to be 0, and if the number of levels matches the number of steps, we might confuse a returned level to mean the index. For example: current_level = max_level = 100 test_level = 0 returned level = 100 In this case 100 means the level, not the index, and _BCM failed. Still, if the _BCL package ordering is descending, the index of level 0 is also 100, so we assume _BQC is indexed, when it's not. This causes all _BQC calls to return bogus values causing weird behavior from the user's perspective. For example: xbacklight -set 10; xbacklight -set 20; would flash to 90% and then slowly down to the desired level (20). The solution is simple; test anything other than the first level (e.g. 1).

This patch removes sti_secondary_start from _INIT section, there are 2 reason for this removal. 1. discarding such a small code does not save much, given the RAM sizes. 2.

tracing_read_pipe zeros all fields bellow "seq". The declaration contains a comment about that, but it doesn't help. The first field is "snapshot", it's true when current open file is snapshot. Looks obvious, that it should not be zeroed. The second field is "started". It was converted from cpumask_t to cpumask_var_t (v2.6.28-4983-g4462344), in other words it was converted from cpumask to pointer on cpumask. Currently the reference on "started" memory is lost after the first read from tracing_read_pipe and a proper object will never be freed. The "started" is never dereferenced for trace_pipe, because trace_pipe can't have the TRACE_FILE_ANNOTATE options.

2013-08-02netlabel: use domain based selectors when address based selectors are not ↵Paul Moore6-158/+130
available NetLabel has the ability to selectively assign network security labels to outbound traffic based on either the LSM's "domain" (different for each LSM), the network destination, or a combination of both. Depending on the type of traffic, local or forwarded, and the type of traffic selector, domain or address based, different hooks are used to label the traffic; the goal being minimal overhead. Unfortunately, there is a bug such that a system using NetLabel domain based traffic selectors does not correctly label outbound local traffic that is not assigned to a socket. The issue is that in these cases the associated NetLabel hook only looks at the address based selectors and not the domain based selectors. This patch corrects this by checking both the domain and address based selectors so that the correct labeling is applied, regardless of the configuration type. In order to acomplish this fix, this patch also simplifies some of the NetLabel domainhash structures to use a more common outbound traffic mapping type: struct netlbl_dommap_def. This simplifies some of the code in this patch and paves the way for further simplifications in the future. Signed-off-by: Paul Moore <[email protected]> Signed-off-by: David S.

2013-08-02net: check net.core.somaxconn sysctl valuesRoman Gushchin1-1/+5
It's possible to assign an invalid value to the net.core.somaxconn sysctl variable, because there is no checks at all. The sk_max_ack_backlog field of the sock structure is defined as unsigned short. Therefore, the backlog argument in inet_listen() shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall is truncated to the somaxconn value. So, the somaxconn value shouldn't exceed 65535 (USHRT_MAX). Also, negative values of somaxconn are meaningless. before: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 net.core.somaxconn = 65536 $ sysctl -w net.core.somaxconn=-100 net.core.somaxconn = -100 after: $ sysctl -w net.core.somaxconn=256 net.core.somaxconn = 256 $ sysctl -w net.core.somaxconn=65536 error: "Invalid argument" setting key "net.core.somaxconn" $ sysctl -w net.core.somaxconn=-100 error: "Invalid argument" setting key "net.core.somaxconn" Based on a prior patch from Changli Gao.

2013-08-02htb: fix sign extension bugstephen hemminger1-1/+1
When userspace passes a large priority value the assignment of the unsigned value hopt->prio to signed int cl->prio causes cl->prio to become negative and the comparison is with TC_HTB_NUMPRIO is always false. The result is that HTB crashes by referencing outside the array when processing packets. With this patch the large value wraps around like other values outside the normal range.
