I've found out about this bug when I tried to build the package for EPEL 6. Submitted it upstream: https://rt.cpan.org/Public/Bug/Display.html?id=71112 Unfortunately, that's not something I can fix myself. If you have experience with endianness bugs, any help is more than welcome. The t/20io-socket-netlink-generic.t:55 test checks serialization of
my $message = $genlsock->new_message(
nlmsg_type => 30,
cmd => 1,
version => 2
);
netlink(7) defines netlink header as:
struct nlmsghdr {
__u32 nlmsg_len; /* Length of message including header. */
__u16 nlmsg_type; /* Type of message content. */
__u16 nlmsg_flags; /* Additional flags. */
__u32 nlmsg_seq; /* Sequence number. */
__u32 nlmsg_pid; /* PID of the sending process. */
};
So I think the expected
00 00 00 14 00 00 00 1e 00 00 00 00 00 00 00 00
is wrong since the type (30 = 0x1e) should occupy two bytes only. Here it spans to nlmsg_flags field.
Still happens on latest Fedora 18 and trying to rebuild perl-Socket-Netlink-0.03-6, moving to rawhide. Thanks & regards, Phil This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.) More information and reason for this action is here: https://fedoraproject.org/wiki/BugZappers/HouseKeeping/Fedora19 This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. Given that this issue is an upstream bug more than it is a packaging issue, I'll be keeping track of it in CPAN's RT. Accordingly, I'm closing this bug with the resolution of UPSTREAM. *** This bug has been marked as a duplicate of bug 1238168 *** |
Description of problem: perl-Socket-Netlink fails to build on PPC as two of the self checks fail, one of them looks like a big endian bug as the result has a swapped bit: t/12netlink-message-header.t ..... ok # Failed test '$message->attrs after unpack' # at t/13netlink-message-attrs.t line 98. # Structures begin differing at: # $got->{str} = '' # $expected->{str} = 'FGH' # Looks like you failed 1 test of 14. t/13netlink-message-attrs.t ...... Dubious, test returned 1 (wstat 256, 0x100) Failed 1/14 subtests t/14netlink-message-error.t ...... ok # Failed test '$message->pack' # at t/20io-socket-netlink-generic.t line 55. # at bytes 0-0xf (0-15) # got: | 00 00 00 14 00 1e 00 00 00 00 00 00 00 00 00 00 |................| # exp: | 00 00 00 14 00 00 00 1e 00 00 00 00 00 00 00 00 |................| # Looks like you failed 1 test of 13.
