Add some Gentoo based patches for better support of static linking.
This are not tested nor supported by upstream developers.
Usage requires presence of several libraries in their static form
which is however not commonly available.
Selinux modified by zkabelac to still work on older sofrware which
did not provided libselinux.pc at a time - see keep the old check
present and use pkg-config only when possible.
Convert naming SYSTEMD_CFLAGS/LIB -> LIBSYSTEMD_CFLAGS/LIBS
to better fit library check for libsystemd.
Build lvmlockd with SD_NOTIFY when we have defined LIBSYSTEMD_LIBS.
When two parallel commands would have tried to create our
/dev/mapper/control node at the same time, one of them could
actually fail even if the 2nd. command actually mknod()
this control node correctly.
So for EEXIST case add detection if the control node is ok.
This may possibly help with some race case in early boot.
With newer kernels (>5.13) DM_CREATE no longer generates
uevent for DM devices without table.
There are even no sysfs block device entries in such case,
although device has asigned major:minor and it is being listed
by 'dmsetup info'.
So this patch calculates amount of 'table' lines and in case
no table line comes from cmdline or stdin - waiting on cookie
is avoided generically instead of disabling just case with
option --notable - which then also skipped handling of an
option --addnodeoncreate (which is however historical and
should be avoided)
As a result there should be no leaking udev cookies and endlessly
waiting commands like this:
dmsetup create mytestdev </dev/null
Add new define 'newline' for use in 'foreach()'
Add new $(SHOW) for makefile printing output
Add 'make print-VAR' for easier debugging of Makefiles' variables.
Commit 73ec3c954b added a way to print
only a part of the report string (repstr) to support decoding individual
string list items out of repstr.
The repstr is normally printed through _safe_repstr_output so that any
JSON_QUOTE character ('"') found within the repstr is escaped to not
interfere with value quoting in JSON format.
However, the commit 73ec3c954b missed
checking the 'len' argument passed to _safe_repstr_output function when
adding the rest of the repstr after all previous JSON_QUOTE characters
were escaped (when calling the last dm_pool_grow_object). When 'len'
is 0, we need to calculate the 'len' ourselves in the function by
simply calling strlen. This is because 'len' is passed to the function
only if we're taking a part of repstr, not as a whole.
In JSON format, we print string list this way:
"key" = "item1,item2,...,itemN"
while in JSON_STD format, we print string list this way:
"key" = ["item1","item2",...,"itemN"]
Before, we stored only the report string itself for a string list
in field->report_string. The field->report_string has either
sorted items or not, depending on what we need for a field -
some report fields have sorted output, some don't...
The field->sort_value.value then contains pointer to the exact
field->report_string. The field->sort_value.items ALWAYS keeps
sorted array of individual items, represented as '[position,length]'
pairs pointing to the field->sort_value.value string.
This approach was fine as far as we didn't need to apply further
formatting to field->report_string. However, if we need to apply
further formatting to field->report_string content, taking into
account individual items, we also need to know where each item
starts and what is its length. Before, we only knew this when
items in report string were sorted, but not in the unsorted version.
We can't rely on the delimiter (default ",") only to separate items
back out of report string, because that delimiter can be contained
in the item value itself.
So this patch enhances the field->report_string for a string list so
it also contains '[position,length]' pairs for each individual item
inside field->report_string. We store this array right beyond the
string itself and we encode it in the same manner we already did for
field->sort_value.items before.
If field->report_string has sorted items, the field->sort_value.items
just points to the array of items we store beyond the report string.
If field->report_string has unsorted items, we store separate array
of items for both field->report_string and field->sort_value.
This patch also cleans up the _report_field_string_list function a bit
so it's easier and more straightforward to follow than the original
version.
Example. If we have "abc", "xy", "defgh" as list on input with ","
as delimiter, then:
- field->report_string will have:
- if we need field->report_string unsorted:
abc,xy,defgh\0{[3,12],[0,3],[4,2],[7,5]}
|____________||________________________|
string array of [pos,len] pairs
|____||________________|
#items items
- if we need field->report_string sorted:
repstr_extra
|
V
abc,defgh,xy\0{[3,12],[0,3],[4,5],[10,2]}
|____________||________________________|
string array of [pos,len] pairs
|____||________________|
#items items
- field->sort_value will have:
- if field->report_string is unsorted:
field->sort_value.value = field->report_string
field->sort_value.items = {[0,3],[0,3],[7,5],[4,2]}
(that is 'abc,defgh,xy')
- if field->report_string is sorted already:
field->sort_value.value = field->report_string
field->sort_value.items = repstr_extra
(that is also 'abc,defgh,xy')
For JSON_STD format, use 'null' if a field has no value at all.
In JSON format, we print undefined numeric values this way:
"key" = ""
while in JSON_STD format, we print undefined numeric values this way:
"key" = null
(Keep in mind that 'null' is different from 0 (zero value) which is
a defined value.)
In JSON format, we print numeric values this way:
"key" = "N"
while in JSON_STD format, we print numeric value this way:
"key" = N
(Where N is a numeric value.)
The original JSON formatting will be still available using the original
DM_REPORT_GROUP_JSON identifier. Subsequent patches will add enhancements
to JSON formatting code so that it adheres more to JSON standard - this
will be identified by new DM_REPORT_GROUP_JSON_STD identifier.
Kernel patch 8b638081bd4520f63db1defc660666ec5f65bc15
introduced support to return UUID in DM_LIST_DEVICES_CMD.
Useful when asking for UUID of each device where the list
could be now returned directly with NAME && UUID for each device.
Returning UUID is done in backward-compatible way. There's one unused
32-bit word value after the event number. This patch sets the bit
DM_NAME_LIST_FLAG_HAS_UUID if UUID is present and
DM_NAME_LIST_FLAG_DOESNT_HAVE_UUID if it isn't (if none of these bits is
set, then we have an old kernel that doesn't support returning UUIDs). The
UUID is stored after this word. The 'next' value is updated to point after
the UUID, so that old version of libdevmapper will skip the UUID without
attempting to interpret it.
It's basically irrelavant which value we assing to optarg,
since it's set by getopt() function, but Coverity tool
is incorrectly reporting possibly dereference of NULL.
Existing mechanism was not able to trace root volume issue.
Simplify the functionality by using simply using activated flag
and trace the dtree in reverse order.
When generating table line for cache target line,
the estimation of added arguments was incorrectly
calculated as the evaluation order of "?" is
made after "+".
However the result was 'masked' by the
