* net: add APIs for manipulating skb page fragments.Ian Campbell2011-08-221-2/+168
| | | | | | | | | | | | | The primary aim is to add skb_frag_(ref|unref) in order to remove the use of bare get/put_page on SKB pages fragments and to isolate users from subsequent changes to the skb_frag_t data structure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to match wireless cards with Intersil firmware that have ID 0x0156:0x0002 and the third ID "Version 01.02". Such cards are currently matched by orinoco_cs, which doesn't support WPA. They should be matched by hostap_cs. The first and the second product ID vary widely, so there are few users with some particular IDs. Of those, very few can submit a patch for hostap_cs or write a useful bugreport. It's still important to support their hardware properly. With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover the remaining Intersil based designs that kept the numeric ID and the "version" of the reference design.

| * | | | move RLIMIT_NPROC check from set_user() to do_execve_common()Vasiliy Kulikov2011-08-111-0/+1

Before the check there was a possibility to greatly exceed the allowed number of processes by an unprivileged user if the program relied on rlimit only. But the check created new security threat: many poorly written programs simply don't check setuid() return code and believe it cannot fail if executed with root privileges. So, the check is removed in this patch because of too often privilege escalations related to buggy programs. The NPROC can still be enforced in the common code flow of daemons spawning user processes. Most of daemons do fork()+setuid()+execve(). The check introduced in execve() (1) enforces the same limit as in setuid() and (2) doesn't create similar security issues. Neil Brown suggested to track what specific process has exceeded the limit by setting PF_NPROC_EXCEEDED process flag. With the change only this process would fail on execve(), and other processes' execve() behaviour is not changed. Solar Designer suggested to re-check whether NPROC limit is still exceeded at the moment of execve(). If the process was sleeping for days between set*uid() and execve(), and the NPROC counter step down under the limit, the defered execve() failure because NPROC limit was exceeded days ago would be unexpected. If the limit is not exceeded anymore, we clear the flag on successful calls to execve() and fork(). The flag is also cleared on successful calls to set_user() as the limit was exceeded for the previous user, not the current one. Similar check was introduced in -ow patches (without the process flag). v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

Together, this implies that the hardware must always be configured to delay a completion IRQ for at least 1 usec or 1 more completion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since sungem_phy is used by multiple, unrelated, drivers make it build as a real module under drivers/net. depmod will pick up the symbol dependency and make sure sungem_phy.ko gets loaded any time sungem.ko or spider_net.ko is loaded.

* | | | af_iucv: add HiperSockets transportUrsula Braun2011-08-131-0/+52
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current transport mechanism for af_iucv is the z/VM offered communications facility IUCV. To provide equivalent support when running Linux in an LPAR, HiperSockets transport is added to the AF_IUCV address family. It requires explicit binding of an AF_IUCV socket to a HiperSockets device. A new packet_type ETH_P_AF_IUCV is announced. An af_iucv specific transport header is defined preceding the skb data. A small protocol is implemented for connecting and for flow control/congestion management.

The issue is where the definition of "sa_family_t" comes from. We've been back and forth on how to fix this issue in the past, see: http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/622621 http://thread.gmane.org/gmane.linux.network/143380 Ben Hutchings suggested we take a hint from how we handle the sockaddr_storage type. First we define a "__kernel_sa_family_t" to linux/socket.h that is always defined. Then if __KERNEL__ is defined, we also define "sa_family_t" as equal to "__kernel_sa_family_t". Then in places like linux/netlink.h we use __kernel_sa_family_t in user visible datastructures. Reported-by: Michel Machado <michel@digirati.com.br> Signed-off-by: David S.
