2007-10-16fix possible NULL deref on low memory condition in capidrv.c::send_message()Jesper Juhl
If we fail to allocate an skb in drivers/isdn/capi/capidrv.c::send_message(), then we'll end up dereferencing a NULL pointer. Since out of memory conditions are not unheard of, I believe it is better to print a error message and just return rather than bring down the whole kernel. Sure, doing this may upset some application, but that's still better than crashing the whole system.

2007-10-10[NET]: Make /proc/net per network namespaceEric W. Biederman
This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

Coverity (1792) spotted a possibly uninitialized return value in case of kmalloc() failure: 1116 static int hisax_cs_setup(int cardnr, struct IsdnCard *card, 1117 struct IsdnCardState *cs) 1119 int ret; 1120 1121 if (!(cs->rcvbuf = kmalloc(MAX_DFRAME_LEN_L1, GFP_ATOMIC))) { 1122 printk(KERN_WARNING "HiSax: No memory for isac rcvbuf\n"); 1123 ll_unload(cs); 1124 goto outf_cs; ... 1165 outf_cs: 1166 kfree(cs); 1167 card->cs = NULL; 1168 return ret; The straightforward solution would be to just add the missing initialization but hardcoding the return value in the out_cs branch (only taken on failure) seems to work just as well and it allows killing a couple of other lines too.

This helps facilitate upcoming use of PCI hotplug API, and in addition makes the code much easier to follow. No code is changed, just moved around.

drivers/isdn/capi/capi.c: In function 'handle_minor_send': drivers/isdn/capi/capi.c:552: warning: cast from pointer to integer of different size Of course, the code here might actually be buggy, in which case this patch should not be applied? Answer: No this field is ignored inside linux kernel.Yes this is ugly, but it's the CAPI spec for all OS. CAPI DATA_B3 Request/Indication CAPI Message has a mandatory field which represent the 32 bit buffer address of the payload data. In linux the payload data do not use a sperate buffer, data follows directely after the CAPI Message in the same skb and we use this assumption inside the drivers, so we can ignore this field. Inside the linux CAPI implemetation we never use this field, so it could also have no value, but since random data in a message is bad as well (e.g. displayed in CAPI traces) we set is to the most adequate value. Outside the kernel the capi20 library sets the correct addresses (there is an optional second field for 64 bit adresses for 64 bit systems, we do not use here).

2007-07-11PCI: Change all drivers to use pci_device->revisionAuke Kok
Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.
