rin 916b154777 libkvm: whitespace 2023-08-23 14:00:11 +00:00
mrg aec4d439cd avoid various use-after-free issues. 
create a ptrdiff_t offset between the start of an allocation region and
some interesting pointer, so it can be adjusted with this offset after
realloc() returns.

found by GCC 12.

rin 03675fcefd Revert CC_WNO_USE_AFTER_FREE from Makefile's (thanks uwe@) 2023-08-03 14:56:36 +00:00
rin 91f8ac6d30 Sprinkle CC_WNO_USE_AFTER_FREE for GCC 12 
All of them are blamed for idiom equivalent to:
	newbuf = realloc(buf, size);
	p = newbuf + (p - buf);

rillig 5f84f05b9b libkvm: suppress lint warnings about extern declarations for now 
This should be properly fixed by someone who is familiar with libkvm, as
it affects <sys/cpu_data.h> as well.

rillig 388550b026 lib: remove CONSTCOND comment 
Since 2021-01-31, lint doesn't need it anymore for the common pattern of
'do ... while (0)'.

christos 104ea67795 Get rid of usrstack/USRSTACK. Document that the old version of getargv is 
broken because of ASLR.

mrg d914a3c1b9 remove clause 3 from all my licenses that aren't conflicting with 
another copyright claim line.  again.  (i did this in 2008 and then
did not update all of my personal templates.)

christos d37b621bc8 Don't treat failure to map the file as fatal. 2020-04-28 14:27:41 +00:00
christos 6b123e2600 make kvm_pread use the mapped buffer if it is available. 2020-04-28 00:19:23 +00:00
christos 39cda3989e Implement kvm_write() for dump files. We map the file privately so that 
changes don't get propagated back, and then write to the private buffer.
This is not useful yes, but it is simple enough to make pread use the buffer
if it is available.

maxv 26cfc3f122 Switch to the new PTE naming. The old naming is now unused, remove it. 2020-04-25 05:17:16 +00:00
chs 86de7c20e3 use a binary search in _kvm_pa2off(). this helps a lot for sparse dumps, 
which can have millions of memory segments.

mrg 35db1fca91 use uint64_t for idx_mask. fixes lookups for some PAs. from skrll. 
bump copyright.  we updated this a lot of this in 2018.

skrll 9181a215b8 Fix _kvm_kvatop so that it now works. 2018-12-18 16:25:47 +00:00
sevan 0f1014292f Reword post mortem description. It tries to get the tree averages if it can. 2018-12-11 23:02:19 +00:00
sevan e67a3558e2 Clarify the difference to getloadavg(3). 2018-12-11 02:29:11 +00:00
mrg 33cbd42a21 tg1 is a 64 bit value, store it in a 64 bit variable. 2018-11-09 04:06:40 +00:00
mrg 19db227738 initialise the kvm errbuf so that if an error occurs, but the 
internal _kvm_*err() functions aren't called, stack garbage is
not reported as an error string.

call _kvm_err() if _kvm_kvatop() fails.  now the above is not
triggered anymore :-)

mrg d89d4475a3 compare matching TG1 bits. 
aarch64 crash dump kvtop now less broken, but still not stable.

- sys/arch/evbarm64 is gone and integrated into sys/arch/evbarm. (by skrll@)
- add support fdt. evbarm/conf/GENERIC64 fdt (bcm2837,sunxi,tegra) based generic 64bit kernel config. (by skrll@, jmcneill@)

maxv 26bc6e1cea Keep /dev/ksyms open in _kvm_open(). This way /dev/ksyms can be put into 
$g_kmem without breaking the tools that need kmem+ksyms.

Discussed on tech-kern@ three weeks ago. The original issue was reported
by maya@, the patch was written by Tom Ivar Helbekkmo, ok christos@.
