Subject: protocol: disable connection reuse for SMB(S)
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=74a169575d6412dc0ff532acdf94de35a6c2a571;p=thirdparty%2Fcurl.git

protocol: disable connection reuse for SMB(S)

Connections should only be reused when using the same "share" (and
perhaps some additional conditions), but instead of fixing this flaw,
this change completely disables connection reuse for SMB. This protocol
is about to get dropped soon anyway.

Reported-by: Osama Hamad
Closes #21238
