rpm: fix rpm -Kv xxx.rpm failed if signature header is larger than 64KB
Since commits [Place file signatures into the signature header where they belong][1] applied, run `rpm -Kv **.rpm' failed if signature header is larger than 64KB. Here are steps: 1) A unsigned rpm package, the size is 227560 bytes $ ls -al xz-src-5.2.5-r0.corei7_64.rpm -rw-------. 1 mockbuild 1000 227560 Jun 3 09:59 2) Sign the rpm package $ rpmsign --addsign ... xz-src-5.2.5-r0.corei7_64.rpm 3) The size of signed rpm is 312208 bytes $ ls -al xz-src-5.2.5-r0.corei7_64.rpm -rw-------. 1 mockbuild 1000 312208 Jun 3 09:48 4) Run `rpm -Kv' failed with signature hdr data out of range $ rpm -Kv xz-src-5.2.5-r0.corei7_64.rpm xz-src-5.2.5-r0.corei7_64.rpm: error: xz-src-5.2.5-r0.corei7_64.rpm: signature hdr data: BAD, no. of bytes(88864) out of range >From 1) and 3), the size of signed rpm package increased 312208 - 227560 = 84648, so the check of dl_max (64KB,65536) is not enough.

4Subject: [PATCH] Bump up the limit of signature header to 64MB
5
6Since commits [Place file signatures into the signature header where they
7belong][1] applied, run `rpm -Kv **.rpm' failed if signature header
8is larger than 64KB. Here are steps:
9
101) A unsigned rpm package, the size is 227560 bytes
11$ ls -al xz-src-5.2.5-r0.corei7_64.rpm
12-rw-------. 1 mockbuild 1000 227560 Jun 3 09:59
13
142) Sign the rpm package
15$ rpmsign --addsign ... xz-src-5.2.5-r0.corei7_64.rpm
16
173) The size of signed rpm is 312208 bytes
18$ ls -al xz-src-5.2.5-r0.corei7_64.rpm
19-rw-------. 1 mockbuild 1000 312208 Jun 3 09:48
20
214) Run `rpm -Kv' failed with signature hdr data out of range
22$ rpm -Kv xz-src-5.2.5-r0.corei7_64.rpm
23xz-src-5.2.5-r0.corei7_64.rpm:
24error: xz-src-5.2.5-r0.corei7_64.rpm: signature hdr data: BAD, no. of
25bytes(88864) out of range
26
27From 1) and 3), the size of signed rpm package increased
28312208 - 227560 = 84648, so the check of dl_max (64KB,65536)
29is not enough.
30
31As [1] said:
32
33 This also means the signature header can be MUCH bigger than ever
34 before,so bump up the limit (to 64MB, arbitrary something for now)
35
36So [1] missed to multiply by 1024.
