When we pv_read() a device that has an orphan vgname, we might need to scan
the system to be sure this is true. However, if the PV has mdas, there's
no way possible for it to have an orphan vgname unless it is a true orphan.
Some areas of the code were optimized to take advantage of this fact, while
others were not (we would still do the expensive scan if a device had mdas
but had an orphan VG).
This patch unifies the code so that every place we are operating on such
a PV, we skip the expensive scan if there are mdas.

This option should be configurable, but for now
do not set it at all.
(lvm2app is used in udisks probers and there
cac cause several nasty races when trying to update
lvmcache during rescan.)
If user try to vgcreate or vgextend non-existent VG,
these messages appears:
# vgcreate xxx /dev/xxx
Internal error: Volume Group xxx was not unlocked
Device /dev/xxx not found (or ignored by filtering).
Unable to add physical volume '/dev/xxx' to volume group 'xxx'.
Internal error: Attempt to unlock unlocked VG xxx.
(the same with existing VG and non-existing PV & vgextend)
# vgextend vg_test /dev/xxx
...
It is caused because code tries to "refresh" cache if
md filter is switched on using cache destroy.
But we can change filters and rescan even without this
machinery now, just use refresh_filters
(and reset md filter afterwards).
(Patch also discovers cache alias bug in vgsplit test,
fix it by using better filter line.)
(VDSO on 32bit is VSyscall on 64bit)
It seems it could be locked on 64bit kernels running 32bit binaries,
but it makes troubles on real 32bit machines where mlock() returns
error when trying to lock such map area. (0xffffe000)
Behavior of mlockall() seems to be similar.
This patch adds a new implementation of locking function instead
of mlockall() that may lock way too much memory (>100MB).
New function instead uses mlock() system call and selectively locks
memory areas from /proc/self/maps trying to avoid locking areas
unused during lock-ed state.
Patch also adds struct cmd_context to all memlock() calls to have
access to configuration.
For backward compatibility functionality of mlockall()
is preserved with "activation/use_mlockall" flag.
As a simple check, locking and unlocking counts the amount of memory
and compares whether values are matching.
For static builds dependency for SELinux libs is not handled by 'ar'.
Till better solution is found, for static builds STATIC_LIBS is used.
Patch updates SELinux detection to use 3rd & 4th parameter for Success/Fail.
Also removes detection of pthread from this check as we know which
version of libdevmapper we are going to link with lvm after merge.
SELinux header check moved to the SELinux test code.
Create new substituted variable PTHREAD_LIBS and link this library
only with tools/libs which really needs it - i.e. dmeventd.
Check for libpthread only for builds with clvmd or dmeventd.
Remove variable LIB_PTHREAD
Modify linking of readline library. Create new substituted varible
READLINE_LIBS - readline library is linked ONLY with tools that really use
it - i.e. lvm. (Static lvm does not use readlin).
Previous behaviour put this library into the variable LIBS and thus
linked it with all created object files of lvm project (i.e. plugins...).
READLINE detection is simplified.
Termcap library is linked in only if readline library doesn't have its own
dependency (i.e. old distributions).
The kernel's blk_stack_limits() function may flag a device as
'misaligned'. If it does the alignment_offset will be -1.
Update set_pe_align_offset() to accommodate this corner case.
- increase timeout to 30 secs (on Chrissie request)
- source both cluster and clvmd for options (like all the other cluster
init scripts)
- add clustered_vgs and _lvs commodity fns
- move rh_status* fns at the top, so they can be reused
- heavily cleanup start and stop fns from redundant code and unnecessary
loops
- improve output from different operations
- make the init script lsb compliant
- don´t force kill of the daemon, send only a TERM signal and then wait
for it to exit
- Resolves rhbz#533247
lvm2 devices have always UUID set even if imported from lvm1 metadata.
Patch removes name argument from dev_manager_info call and converts
all activation related calls to use query by UUID.
Also it simplifies mknode call (which is the only user on mknodes parameter).
