You can probably try stuffing multiple consecutive slashes ('/') and they should be normalized into one. You can also play with "/./" if the program wasn't happy with consecutive slashes. Chi-Hsuan Yen via aur-general <aur-general@archlinux.org>于2017年8月8日周二 22:39写道：
That's a great solution! But it doesn't have to be the same length actually. A shorter path with padded 0x00s should also work fine.

Hello Arch enthusiasts,
I'd like to create a package for Pulse Connect Secure, a popular VPN software. Current PKGBUILD can be found at [1]. That package works fine, but it conflicts with Arch's packaging guideline. [2]
"Packages should never be installed to /usr/local"
The reason I put files in /usr/local is that file paths are
apparently
hard-coded. Specifically, the VPN frontend (pulseUi) loads assets from /usr/local/pulse/html, and then it invokes /usr/local/pulse/pulsesvc to actually connects to VPN.
Is there a workaround for this?
Not much you can do with software which encodes violations of

/usr/local/pulse *gags*
If software insists on being installed to "/completely/arbitrary/directory" then you either package it anyway or you don't. But I suppose you could try asking them to install it in /opt instead.

Aha, didn't think of patching. That simple "fix" works! Many thanks! The key is that the path before and after should have the same length. [1]

Tailing null bytes sounds absolutely interesting. But I get no luck for this package. There's a line in the offensive binary:
file:////\x0/usr/local/pulse/\x0/html/
(\x0 indicates a null byte)
I tried several combinations:
file:////\x0/opt/pulse/\x0\x0\x0\x0\x0\x0\x0/html/ file:////\x0/opt/pulse//html/\x0\x0\x0\x0\x0\x0\x0 file:////\x0/opt/pulse/\x0/html/\x0\x0\x0\x0\x0\x0
Some doesn't run, and others uses a wrong path:
(pulseUi:1501): Gtk-WARNING **: Error loading icon from file '/opt/pulse/': Image file '/opt/pulse/' contains no data
or
(pulseUi:9589): Gtk-WARNING **: Error loading icon from file '/opt/pulse//html//html/images/Pulse-Secure128x128.png': Failed to open file '/opt/pulse//html//html/images/Pulse-Secure128x128.png': No such file or directory
I think sticking to same-size patching is simpler :)
