net: Fix wrong interpretation of some copy_to_user() results.

2008-05-01T21:44:32Z

[ Upstream commit: 653252c2302cdf2dfbca66a7e177f7db783f9efa ] I found some places, that erroneously return the value obtained from the copy_to_user() call: if some amount of bytes were not able to get to the user (this is what this one returns) the proper behavior is to return the -EFAULT error, not that number itself.

[NET]: Make /proc/net per network namespace

2007-10-10T23:49:06Z

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.

jprobes: remove JPROBE_ENTRY()

2007-07-19T17:04:44Z

AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything useful - so remove it .. I've left a do-nothing version so that out-of-tree jprobes code will still compile without modifications.

[CCID3]: More to see in dccp_probe

2007-04-26T05:26:56Z

This adds a few more fields of interest to /proc/net/dccpprobe, the following output ensues: 1 2 3 4 5 6 7 8 9 10 11 sec.usec src:sport dst:dport size s rtt p X_calc X_recv X t_ipi Also made the formatting consistent.

[PATCH] mark struct file_operations const 7

2007-02-12T17:48:46Z

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[DCCP]: Introduce dccp_probe

2006-09-24T21:08:17Z

This adds DCCP probing shamelessly ripped off from TCP probes by Stephen Hemminger. I've put in here support for further CCID3 variables as well. Andrea/Arnaldo might look to extend for CCID2. Signed-off-by: Ian McDonald Signed-off-by: Arnaldo Carvalho de Melo
