* [PATCH] sysctl: fix sys_sysctl interface of ipc sysctlsEric W. Biederman2006-12-08
| | | | | | | | | | | | | Currently there is a regression and the ipc sysctls don't show up in the binary sysctl namespace.

* [PATCH] sysctl: simplify ipc ns specific sysctlsEric W. Biederman2006-12-08
| | | | | | | | | | | | | | | Refactor the ipc sysctl support so that it is simpler, more readable, and prepares for fixing the bug with the wrong values being returned in the sys_sysctl interface. The function proc_do_ipc_string() was misnamed as it never handled strings. It's magic of when to work with strings and when to work with longs belonged in the sysctl table. I couldn't tell if the code would work if you disabled the ipc namespace but it certainly looked like it would have problems. Signed-off-by: Eric W.

* [PATCH] sysctl: implement sysctl_uts_string()Eric W. Biederman2006-12-08
| | | | | | | | | | | | The problem: When using sys_sysctl we don't read the proper values for the variables exported from the uts namespace, nor do we do the proper locking. This patch introduces sysctl_uts_string which properly fetches the values and does the proper locking. Signed-off-by: Eric W.

* [PATCH] sysctl: simplify sysctl_uts_stringEric W. Biederman2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The binary interface to the namespace sysctls was never implemented resulting in some really weird things if you attempted to use sys_sysctl to read your hostname for example. This patch series simples the code a little and implements the binary sysctl interface. In testing this patch series I discovered that our 32bit compatibility for the binary sysctl interface is imperfect. In particular KERN_SHMMAX and KERN_SMMALL are size_t sized quantities and are returned as 8 bytes on to 32bit binaries using a x86_64 kernel. However this has existing for a long time so it is not a new regression with the namespace work. Gads the whole sysctl thing needs work before it stops being easy to shoot yourself in the foot. Looking forward a little bit we need a better way to handle sysctls and namespaces as our current technique will not work for the network namespace. I think something based on the current overlapping sysctl trees will work but the proc side needs to be redone before we can use it. This patch: Introduce get_uts() and put_uts() (used later) and remove most of the special cases for when UTS namespace is compiled in. Signed-off-by: Eric W.

* [PATCH] fault injection: stacktrace filteringAkinobu Mita2006-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides stacktrace filtering feature. The stacktrace filter allows failing only for the caller you are interested in. For example someone may want to inject kmalloc() failures into only e100 module. they want to inject not only direct kmalloc() call, but also indirect allocation, too. - e100_poll --> netif_receive_skb --> packet_rcv_spkt --> skb_clone --> kmem_cache_alloc This patch enables to detect function calls like this by stacktrace and inject failures. The script Documentaion/fault-injection/failmodule.sh helps it. The range of text section of loaded e100 is expected to be [/sys/module/e100/sections/.text, /sys/module/e100/sections/.exit.text) So failmodule.sh stores these values into /debug/failslab/address-start and /debug/failslab/address-end. The maximum stacktrace depth is specified by /debug/failslab/stacktrace-depth.

* [PATCH] ISDN: Avoid a potential NULL ptr deref in ipppJesper Juhl2006-12-08
| | | | | | | | | | | | | | | | There's a potential problem in isdn_ppp.c::isdn_ppp_decompress(). dev_alloc_skb() may fail and return NULL. If it does we will be passing a NULL skb_out to ipc->decompress() and may also end up dereferencing a NULL pointer at *proto = isdn_ppp_strip_proto(skb_out); Correct this by testing 'skb_out' against NULL early and bail out.

| | | | | | | | | | | | Save 3 indent levels in interrupt routine by moving the code to a separate function. This needs to be done to allow Lindent do its work, since only 4 columns are used for indenting now and hence Lindent makes a big mess in the code, when moves it 4*5 columns to the right.
