2007-02-12[XFRM]: Fix OOPSes in xfrm_audit_log().David S. Miller3-11/+19
Make sure that this function is called correctly, and add BUG() checking to ensure the arguments are sane. Based upon a patch by Joy Latten. Signed-off-by: David S. Miller <[email protected]>
2007-02-12[TCP]: cleanup of htcp (resend)Stephen Hemminger1-28/+37
Minor non-invasive cleanups: * white space around operators and line wrapping * use const * use __read_mostly Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2007-02-12[TCP]: Use read mostly for CUBIC parameters.Stephen Hemminger1-10/+10
These module parameters should be in the read mostly area to avoid cache pollution. Signed-off-by: Stephen Hemminger <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2007-02-12[NETFILTER]: nf_conntrack_tcp: make sysctl variables staticPatrick McHardy1-3/+3
sysctls are registered by the protocol module itself since 2.6.19, no need to have them visible to others. Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2007-02-12[NETFILTER]: ip6t_mh: drop piggyback payload packet on MH packetsMasahide NAKAMURA1-0/+7
Regarding RFC3775, MH payload proto field should be IPPROTO_NONE. Otherwise it must be discarded (and the receiver should send ICMP error). We assume filter should drop such piggyback everytime to disallow slipping through firewall rules, even the final receiver will discard it.

2007-02-12[NETFILTER]: nf_conntrack: change nf_conntrack_l[34]proto_unregister to voidPatrick McHardy3-35/+9
No caller checks the return value, and since its usually called within the module unload path there's nothing a module could do about errors anyway, so BUG on invalid conditions and return void. Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2007-02-12[NETFILTER]: nf_conntrack: fix invalid conntrack statistics RCU assumptionPatrick McHardy3-9/+15
NF_CT_STAT_INC assumes rcu_read_lock in nf_hook_slow disables preemption as well, making it legal to use __get_cpu_var without disabling preemption manually. The assumption is not correct anymore with preemptable RCU, additionally we need to protect against softirqs when not holding nf_conntrack_lock. Add NF_CT_STAT_INC_ATOMIC macro, which disables local softirqs, and use where necessary. Signed-off-by: Patrick McHardy <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2007-02-12[PATCH] ps3: Virtual Frame Buffer DriverGeert Uytterhoeven5-0/+1295
Add the PS3 Virtual Frame Buffer Driver. As the actual graphics hardware cannot be accessed directly by Linux, ps3fb uses a virtual frame buffer in main memory. The actual screen image is copied to graphics memory by the GPU on every vertical blank, by making a hypervisor call.

2007-02-12[PATCH] ps3: Preallocate bootmem memory for ps3fbGeert Uytterhoeven2-0/+51
Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.

2007-02-12[PATCH] fb_videomode_to_var: reset virtual screen parametersGeert Uytterhoeven1-2/+6
fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members.
