X-Git-Tag: REL_14_9~11 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=341996248e4d720556689e5fb3da7a408cf94228;p=thirdparty%2Fpostgresql.git Raise fixed token-length limit in hba.c. Historically, hba.c limited tokens in the authentication configuration files (pg_hba.conf and pg_ident.conf) to less than 256 bytes. We have seen a few reports of this limit causing problems; notably, for moderately-complex LDAP configurations. Increase the limit to 10240 bytes as a low-risk stop-gap solution. In v13 and earlier, this also requires raising MAX_LINE, the limit on overall line length. I'm hesitant to make this code consume too much stack space, so I only raised that to 20480 bytes.
