asprintf() allocates memory which is not freed on the error path of
get_task_name(), thus potentially leading to memory leaks.
%m specifier on fscanf allocates memory, too, which needs to be freed by
the caller.
This reworks get_task_name() to avoid memory allocation.
- Pass a buffer and its length to the function, similarly to what
get_command_name() does, thus avoiding to allocate memory for
the string to be returned;
- Use snprintf() instead of asprintf();
- Use fgets() instead of fscanf() to limit string length.

vdpa header file is already present in the tree at
vdpa/include/uapi/linux/vdpa.h and used by vdpa/vdpa.c.
As we discussed in thread [1] vdpa header comes from a different
tree, similar to rdma subsystem. Hence remove the duplicate vdpa
UAPI header file.

NETROM uses AX.25 addresses so this is a simple wrapper around ax25_ntop1.

AX.25 addresses are based on Amateur radio callsigns followed by an SSID
like XXXXXX-SS where the callsign is up to 6 characters which are either
letters or digits and the SSID is a decimal number in the range 0..15.
Amateur radio callsigns are assigned by a country's relevant authorities
and are 3..6 characters though a few countries have assigned callsigns
longer than that. AX.25 is not able to handle such longer callsigns.
Being based on HDLC AX.25 encodes addresses by shifting them one bit left
thus zeroing bit 0, the HDLC extension bit for all but the last bit of
a packet's address field but for our purposes here we're not considering
the HDLC extension bit that is it will always be zero.
Linux' internal representation of AX.25 addresses in Linux is very similar
to this on the on-air or on-the-wire format. The callsign is padded to
6 octets by adding spaces, followed by the SSID octet then all 7 octets
are left-shifted by one byte.
This for example turns "LINUX-1" where the callsign is LINUX and SSID is 1
into 98:92:9c:aa:b0:40:02.

We started to use in-kernel filtering feature which allows to get only
needed tables (see iproute_dump_filter()). From the kernel side it's
implemented in net/ipv4/fib_frontend.c (inet_dump_fib), net/ipv6/ip6_fib.c
(inet6_dump_fib). The problem here is that behaviour of "ip route save"
was changed after
c7e6371bc ("ip route: Add protocol, table id and device to dump request").
If filters are used, then kernel returns ENOENT error if requested table
is absent, but in newly created net namespace even RT_TABLE_MAIN table
doesn't exist. It is really allocated, for instance, after issuing
"ip l set lo up".
Reproducer is fairly simple:
$ unshare -n ip route save > dump
Error: ipv4: FIB table does not exist.
Dump terminated
Expected result here is to get empty dump file (as it was before this
change).
v2: reworked, so, now it takes into account NLMSGERR_ATTR_MSG
(see nl_dump_ext_ack_done() function). We want to suppress error messages
in stderr about absent FIB table from kernel too.
v3: reworked to make code clearer. Introduced rtnl_suppressed_errors(),
rtnl_suppress_error() helpers. User may suppress up to 3 errors (may be
easily extended by changing SUPPRESS_ERRORS_INIT macro).
v4: reworked, rtnl_dump_filter_errhndlr() was introduced. Thanks
to Stephen Hemminger for comments and suggestions
v5: space fixes, commit message reformat, empty initializers
