[TCP]: Congestion control API RTT sampling fix

2007-06-15T22:08:43+00:00

Commit 164891aadf1721fca4dce473bb0e0998181537c6 broke RTT sampling of congestion control modules. Inaccurate timestamps could be fed to them without providing any way for them to identify such cases. Previously RTT sampler was called only if FLAG_RETRANS_DATA_ACKED was not set filtering inaccurate timestamps nicely. In addition, the new behavior could give an invalid timestamp (zero) to RTT sampler if only skbs with TCPCB_RETRANS were ACKed. This solves both problems.

declare struct ktime

2007-05-09T19:30:54+00:00

Some smarty went and inflicted ktime_t as a typedef upon us, so we cannot forward declare it. Create a new `union ktime', map ktime_t onto that. Now we need to kill off this ktime_t thing.

[PATCH] fix MTIME_SEC_MAX on 32-bit

2007-03-17T02:25:07+00:00

The maximum seconds value we can handle on 32bit is LONG_MAX. Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] hrtimers: add high resolution timer support

2007-02-16T16:13:59+00:00

Implement high resolution timers on top of the hrtimers infrastructure and the clockevents / tick-management framework. This provides accurate timers for all hrtimer subsystem users.

[PATCH] Numerous fixes to kernel-doc info in source files.

2007-02-11T18:51:32+00:00

A variety of (mostly) innocuous fixes to the embedded kernel-doc content in source files, including: * make multi-line initial descriptions single line * denote some function names, constants and structs as such * change erroneous opening '/*' to '/**' in a few places * reword some text for clarity Signed-off-by: Robert P.

[PATCH] ktime: Fix signed / unsigned mismatch in ktime_to_ns

2006-12-07T16:39:37+00:00

The 32 bit implementation of ktime_to_ns returns unsigned value, while the 64 bit version correctly returns an signed value. There is no current user affected by this, but it has to be fixed, as ktime values can be negative.

[PATCH] prevent timespec/timeval to ktime_t overflow

2006-09-06T18:00:02+00:00

Frank v. Waveren pointed out that on 64bit machines the timespec to ktime_t conversion might overflow. This is also true for timeval to ktime_t conversions. This breaks a "sleep inf" on 64bit machines. While a timespec/timeval with tx.sec = MAX_LONG is valid by specification the internal representation of ktime_t is based on nanoseconds. The conversion of seconds to nanoseconds overflows for seconds values >= (MAX_LONG / NSEC_PER_SEC). Check the seconds argument to the conversion and limit it to the maximum time which can be represented by ktime_t.
